The Reloading Press was a feature that ran steady for a while here on GB, but I lost track of it when I got busy publishing. But recently, I’ve been hearing noises about a new “best cartridge ever.” Well, that’s what nearly all new cartridge promise. Even so, this one was very interesting, and it combines two features I like – and that GURPS likes – in one place. A long, narrow, high sectional density bullet, plus a shorter, fatter case which gives a nice starting volume to keep pressure high.

.224 Valkyrie (5.7x41mm)

The .224 Valkyrie takes the basic case in one of my favorite cartridges for GURPS (and not bad in real life, too), the 6.8x43mm SPC, and then launches a long, narrow bullet from it with the same barrel diameter as the base .223/5.56x45mm NATO bullet.

It was developed in 2017, and really looks an awful lot like someone was playing with the GURPS ballistics calculator I developed. They weren’t, of course, but . . . well, see for yourself.

The basic concept takes a normal 6.8SPC case and launches a very heavy, long .223 bullet out of it. The standard load is 90 grains, whereas a usual match-grade or longer range .223 is 69 to 77 grains (depending on manufacturer). So this is going to be a bullet that really wants to not slow down . . . and you bet, one of the intended uses for the .224 Valkyrie is to ring bells to 1,000m while still remaining supersonic, which is about 350m/s.

The usual contender, the 62gr M855, or the improved Mk318 or M855A1, fall to the speed of sound at about 570m using my calculator, which says “accurate to 500-600m” out of the shorter barrel weapons that’s their design platform, and about 630m out of a 20″ barrel.

So what happens when you fling a 90 grain bullet out of a 20″ barrel? Nice things.

Ballistic’s Calculator Inputs


Basic inputs for the calculator are as follows, selecting 406mm for the barrel length.

INPUT
.224 Valkyrie
Chamber Pressure 55000 psi
Barrel bore 5.7 mm
Case Length 41 mm
Chamber Bore 10.7 mm
Barrel length 508 mm
Bullet Mass 90 grains
Aspect Ratio 5.4 L/Bore
Burn length 14.66 mm
Projectile Caliber 5.7 mm
Total Accelerated Mass 90 grains
Expansion Ratio 2 expansion
Projectile Load 1

 

Output Stats
 
The rifle develops appreciable damage at pistol-length barrels, at least within the assumptions of the calculator. Why you would want to do this is another question, and putting all of that powder out of a 5″ (127mm) barrel is an exercise in gratuitous fireball generation (OK, maybe that’s why you’d want to do it).
At longer barrels – which is the entire point of the round – it comes into its own. Out of a 14.5mm carbine barrel, it’s still going to hit for 5d or 5d+1 and stay supersonic to 750m. With a target rifle of 20 to 24″, the calculator suggests nearly 6d penetration and an accurate range pushing 850m…and it will tumble and fragment (and not drop down to pi- instead of pi) to 220m out of a carbine and 320m out of a rifle-length platform. And that’s no joke.
Real-world data, rather than my calculator, pushes that supersonic distance to something like 1,250m with the right barrel and bullet. This thing can reach a long, long way. (Max range, not shown, is probably 4,550m with my calculator.).
So, here’s the chart:
Half-Damage Range 661
AP Wound Channel 0.5
Normal Channel 1.4
Barrel Length(mm) Barrel Length (in) Velocity (m/s) Muzzle Energy (J) Damage D&D Damage Supersonic (m) Pi to pi- (m)

Notes
  • The velocity is at the muzzle. The velocity with a 20″ barrel is tuned to match real-world data at 2700 fps, which is the long, heavy bullet designed to carry farther, rather than develop the most energy at the muzzle.
  • The pi to pi- range is where the damage drops from piercing to small piercing. For very short barrels (smaller than 177mm in my model), the bullet is slow enough that it will not yaw and fragment, and so it’s only good for pi- rather than pi. This is defined as 600m/s in my model, which is somewhat arbitrary.
  • It’s possible that the damage (penetration, really) is perhaps 10% high. That would still give a 20″ barrel about 5d+2, and a 14.5″ barrel a full 5d out of an M4 platform.
At any useful barrel length for a rifle cartridge, that is, about 9″ and higher (and that’s a darn short rifle), there is some range at which it will do its full pi damage type. At carbine length and above (14.5″) this is measured in hundreds of meters; this is a good choice at moderate range as well as long.
For GURPS gunners, it’s a good cartridge, though not a great one, I think. The long range is short-changed in the calculator vs reality, and the difference between (say) a 320m range where it drops to pi- and a 660m 1/2D range is pretty far beyond the usual engagement distances for PCs. You do get rifle-size penetration out of a carbine-sized platform, though, which is nice. I suspect recoil is manageable as well.
Where this will do well is if you don’t want to lug around an 9-11 lb rifle in the form of a .308, which has a lower tumble range (250m) and a lower 1/2D range (575m) than the 320m and 660m of the .224 Valkyrie. If the 7.62 actually drops from pi to pi- when it drops below 600m/s or so, then there’s a weird case where at 250-350m, and then between 575 and 660m you’re better off with the .224 Valkyrie, but at other ranges you’re better off injury-wise with the .308. That’s cutting it pretty fine: what in general this means is that with a full-length rifle in both cases, you can go with a lighter platform (AR15 rather than FN-FAL, AR-10 based). That can save you three to five pounds on your arms. Also, the ammunition is lighter and the magazines bigger for the .224 Valkyrie.
For GURPS, though, you really need to care about reaching out a long, long way with a lightweight weapon before this becomes something you’re looking at seriously. Ironically, where the 6.8SPC got somewhat of a “meh” reaction in the real world, in GURPS it’s like the .40S&W – a goldilocks cartridge where everything is “just right.” At 6d it’ll drop Joe Average to -HP in one shot, and 3d to the vitals at distance is still a potential lethal dose through light body armor.
Platforms
 
You need a purpose-built upper receiver (or at least a barrel, chamber, and bolt change) to shoot this cartridge. The thing is going to look like every other AR-15 style rifle out there on the outside, and you’ll spend (in 2019) anywhere from $350 to 700 to get one…unless for whatever reason you want/need to spend more (for things like super-custom, which is frequently a great excuse to buy Weapon Bond).
So no real details or special platform list today! This modification gives you a bit more penetration, a bit more range, and a bit heavier ammunition out of a barrel that’s the same bore as a standard M16/AR15. It does this by increasing the size of the cartridge case, which keeps the pressure higher as the bullet goes down the barrel, and by shooting a round that’s probably going to be 50% heavier than the one you launch out of your standard M16 type platform. For carbine users, this is a good thing, in a way, because it retains its full damage 50% farther than the lighter round (though both have roughly the same 220m or so range to where they both drop to pi- from pi).

Since 2013 or so, I’ve done a GURPSDay post, where I collect GURPS-related posts and publish links. For years, I was able to do this like clockwork, every Thursday morning, which is the release day for GURPS products for SJG. That got a bit . . . squishy . . . as I got busy with publishing, and some days I’d miss. Sometimes I caught it, sometimes not until the next week.

Well, GURPSDay is going through some changes. I’ve finally sat down and figured out how to get WordPress to do what I want it to, more or less.

I’ve finally got a blog roll. Look to the right, and you’ll see any recent posts from blogs I follow. No excerpts, just titles, dates, and author names if they’re provided in the stream.

Also, there’s a new GURPSDay RSS Feed page. This will be updated twice daily, and displayed in reverse chronological order. It displays the most recent 50 posts (which these days covers about three weeks), provides an excerpt of 65 words per posts, and might display an image one day. It’s supposed to, but that requires cooperation on my blog, the plugin, and the target blogs.

So you can check out the most recent GURPS content any time you like.

Game on!

It’s another GURPSDay, and here’s the last few weeks of posts! This post has been updated to go through Nov 8. Scroll all the way down (the random order is, well, random). Catch up and get some repeat views and if you missed some. They’re in reverse chronological order, so if you’re up-to-date, just skim off the top!

We got a great new blog this week: Dark Journeys, by GURPS Author, Historian, and friend of mine Shawn Fisher. It’s a near-guaranteed to be a good read.

News for Gaming Ballistic:

  • The Nordlond Sagas kickstarter keeps plugging away in production. Hand of Asgard has all its art. I’ve seen all the rough colors for Nordlondr Folk. Making editing progress on Forest’s End, but slower than I’d like. Real Life (trying to sell a house, and it’s not going well) keeps kicking me.
  • Four Perilous Journeys made landfall on Nov 1 in the USA, and should be ready to start shipping out by the end of the week!

GURPSDay is in its sixth – GURPSDay started in February 2013,  a year after I started Gaming Ballistic. Things have slowed down a bit, and I’ll be considering how to revitalize this weekly activity. I’d like to see an average of 100 posts here per week – one per blog, ish – so we’ll see what we can do to get creative juiced flowing.If you just started a GURPS blog – and I know that some of you have – email me and get on the list! With the advent of the Dungeon Fantasy RPG, Powered by GURPS, there’s even more reason to write.

How? Two action items: post more, recruit more. It’s really that simple. More posters is more posts, and more interest in GURPS.

Below you can find the blog activity for the last week. There’s a whole lotta awesome GURPS going on. Read all the posts.

Not every blog posts about GURPS every week, but some are ridiculously prolific! The list is randomized, so different bloggers will be highlighted at the top of the post each week.

  • Four Perilous Journeys is arriving for international backers, and they seem quite pleased. The books will make landfall on Nov 1 in the USA, and hopefully travel to Studio 2 in time to start shipping those out for US folks such that they arrive before Turkey Day. Canadian backers with card decks and counter sheets? You guys get taken care of with the US folks.

News for Gaming Ballistic:

  • The Nordlond Sagas kickstarter closed. It funded and hit just shy of $25,000, but achieved a lower backer count than Hall of Judgment.
  • Nonetheless, it was close enough to the offset print stretch goal – maybe $100-200 or so between the print costs for POD vs printing it in Latvia – that I decided to declare the goal achieved anyway.
  • The next step is Backerkit, and getting some idea of shipping sorted out. Since this is “all books,” I will work shipping out and get Backerkit open as soon as possible.
  • Four Perilous Journeys should start shipping this week to international backers. Still working through some shipping customs details on getting the books to the USA, and as soon as that form is filled out, they’ll be ready to go. Expect a month to get to TN, then another 1-3 weeks, and then all stuff will be in hand.

News for Gaming Ballistic:

  • The Nordlond Sagas kickstarter funded, but is having one of the worst cases of the doldrums I’ve yet experienced. About $100 per day for the last 16 days. Fortunately, there are well over 400 folks following but not yet pledged, so there’s a lot of opportunity to hit the $29K stretch goal, and that’s between 145-150 pledges, so there’s still a good shot at that goal. The authors’ manuscripts are starting to come in in more-final form, and those extra pages are going to be needed!
  • The swords and shields from Nordvorn were completed and shipped, save for one where the backer asked me to wait since he won’t be in town. No problem there.
  • The card decks for Four Perilous Journeys have all arrived at the distributors. The die-cut counters shipped out to the UK last night, should arrive in a week or so. The printing of 4PJ was schedule to complete today, but with time differences to Latvia by the time I am at a computer, they’re gone for the evening. And it’s a weekend. I suspect we’ll be ready to parse up the shipment and get it going on Monday.

It’s another GURPSDay, and here’s the last few weeks of posts! The Nordlond Sagas Kickstarter continues to hum along, though we’re in the ‘doldrums’ period where things are flat. Even so, we’re still projected to clear the last stretch goal, and have enough “latent” backers to exceed it by a significant margin if they all come in at the end (they won’t), to the tune of “best GB Kickstarter yet.” As of now, we will probably come in between Nordvorn at $26K and Four Perilous Journeys at $40K. That’s not nothing.

News for Gaming Ballistic:

  • The last Dungeon Grappling books that were pending were put in the mail and are on their way. THAT’S done.
  • The swords and shields that were on hold first due to subzero temps and then due to a house move will be completed this week. They’ll ship out Real Soon Now.
  • All goods for Four Perilous Journeys are in production or better. The books should be done next week. The card decks are on their way, and have already arrived in the UK. The cardboard die-cut counters started shipping yesterday. At this moment, all is well.
  • As mentioned, the Nordlond Sagas kickstarter had a strong start, but could use a bit more visibility. A reshare of the link or talking about why you’re excited about it (presuming you are) would help. What is needed is more reach for the work. The Kickstarter ends Oct 12.

It’s another GURPSDay, and here’s the last few weeks of posts! My 8th Kickstarter, Norðvorn Sagas, launched on September 10, and funded on the 17th! We are now at 125% funding with more than three weeks to go. Given the trajectory of Kickstarters, we’re estimated by BackerTracker to hit over $30,000, well past the highest stretch goal. With help, we may even do better. This was helped a whole lot by a surprise addition.

The Hand of Asgard presents additional options and guidelines presented for Clerics who choose to devote themselves to the worship of just one instead of the pantheon as a whole. Also included are more than twenty new Holy Might abilities available for Asgardian Clerics and Holy Warriors to bring the word . . . or the sword . . . to those that need it. The book is 16 pages long, in 8×10 format. It is available as an add-on to a pledge level, rather than as part of an existing pledge.

  • The proof of Dungeon Grappling to finally finish all the physical rewards for Citadel at Nordvorn came in brilliantly (if months late). I got 100 of them printed, and the’re on the way to me (PubGraphics expedited the printing). They should be in the mail Tuesday. Finally.
  • I ordered all physical goods for Four Perilous Journeys except for the international card decks and counter tiles. Still working on CE Mark issues; need to chat with folks. Might have found a better option for the cards, but not the cardboard chits.
  • All five files for Four Perilous Journeys were accepted and the books will be ready to ship by October 4! 100 of each book will go to the UK for international distribution, and the balance come to the USA.
  • I announced the approval of the Nordlond Enemies Book (tentatively titled Norðlondr Óvinabókin) as my next approved Dungeon Fantasy RPG project. I’ve actually got an idea for a companion book that should be a very tasty treat.

It’s another GURPSDay, and here’s the last few weeks of posts! The Dungeon Fantasy Magic Items 2 Kickstarter came and went, and was super-close – like less than $950 – from getting to its singular stretch goal of 64 pages instead of 48. All may not be lost, however, and the Backerkit phase will start when SJG is ready.

The other big news is that if you want more Dungeon Fantasy RPG, well, you can have it. My 8th Kickstarter, Norðvorn Sagas, launched this past Tuesday. It had the strongest first day of any Kickstarter I’ve yet launched, even better by a few bucks than Four Perilous Journeys. It’s currently sitting just shy of 80% funding, and is roughly halfway to the “300 physical orders” first stretch goal. Given the trajectory of Kickstarters, we’re in a good position to threaten the $29K stretch goal as well, but of course we need help.

  • My second print proof on Dungeon Grappling has still not arrived, despite being told it was on the way nine days ago. I’m starting to think I need a new PoD company. That’s a real shame..
  • I ordered all physical goods for Four Perilous Journeys except for the international card decks and counter tiles. There are some lingering questions on whether Kickstarter rewards not available through retail must be certified/marked with CE Mark. I don’t THINK so, but I need to chat with folks.
  • I have not yet heard back from my printer on whether the Four Perilous Journeys files have been accepted. This is odd, and I’m also waiting for some quotes from them, so I will keep at it. Weird week for communication.
  • I announced the approval of the Nordlond Enemies Book (tentatively titled Norðlondr Óvinabókin) as my next approved Dungeon Fantasy RPG project. It’s still in the future, but if the current KS takes off and we hit somewhere around the $75,000 level (yes, this is ‘irrationally exuberant given that level of funding usually requires a first-two-day total on the order of $20-25K) I can self-fund it.
