no the wssm stuff was olympic arms and they had proprietary upper, bolt, carrier and barrel extension to make it work in the ar15. if you happen to find all the parts yes i could make a barrel if you want to rent the reamer.

Would anyone like to see a 223 Wildcat that's optimized for the newer heavy Valkyrie bullets?  Shorten the case just enough to seat something like a 90gr Sierra Match King or 80gr Hornady ELD.  The case might end up basically being a .224 Wolverine.  I'd say it would allow for loading the 95gr and 88gr bullets that those would really eat up case capacity.

So would something like this offer anything that realistically couldn't be done with a 75/77 grain match bullet in a 223?  Would the velocities be worth the effort?  And how well would a shorter case work with something like a 69gr SMK in case a guy wanted to "go cheap" and buy the 69s over the more expensive pills?

I may be completely wrong, but the lost case capacity combined with the heavier bullet would mean significant velocity drops, which is completely antithetical to the idea of making a .224 Valkyrie lite.  The only thing you gain from trimming the case is being able to feed the longer bullets from a magazine.  So unless you really need semi-auto function instead of loading the cartridge long and single loading rounds when firing, I don't see a beneficial tradeoff.  Otherwise I'd say use a .223 AI for the extra capacity so deeper seated bullets wouldn't be as much a problem.

I suppose a trimmed back .223 with an AI-like shoulder might give you similar capacity to the original .223 while also giving magazine compatibility for longer bullets.  But I don't have anything to do the exact calculations on that.

The velocity certainly won't be there.  Not compared to the Valkyrie.  Will the high BC compensate for the lower velocity? 

Just playing with a ballistics calculator I found online, and guessing that this little cartridge would push a 90gr Sierra to 2,350 FPS, it looks like the theoretical cartridge would be 119" low at 600 yards with a 100 yard zero.  The 223 Remington, loaded with a 77gr SMK at 2,650 FPS would be 113" low at the same distance.  So maybe there's no reason to mess with the idea further.

I don't think it will be enough.  This sounds similar to why they halted the 6.5 Mongrel development.  The longer, high BC 6.5 bullets everyone would have wanted to shoot took up too much case capacity and the velocity just wasn't there to make it appealing.

I always wanted to see if I could get a 8mm kurtz AR 10.

We are testing the 8mm Maverick based on the Dasher case like the Timberwolf and Sabercat; it out-performs the Kurz, but in the AR15.  i will be doing a magnum cased 8mm too for the AR10

I remain anxious for the .20 Viper.  Being based on the Mongoose case, it should out-perform the Practical (which I was hot for... until BD told me about the Viper). I've already stocked up on bullets...  [biggrin]

I originally stumbled on to this forum looking for information about the .30 Herrett AR. I had never heard of the .277 WLV but now I have one of those I'll be playing with pretty soon (Thanks again Mark). I still have a keen interest in the .30 HAR  so would like to see barrels offered for it. The 6x45 is interesting to me also along with the TCU rounds, I have been messing around with Contenders and Encores for many moons.

If you like the TCU rounds- check out the 6mm Mongoose, 257 Ocelot, and soon to be the .20 Viper. They are sort of an AR version of the TCU line, only MDWS line. The 6mm Mongoose puts out greater numbers, accuracy is there too, than the 6x45. If you want to kick it up a notch energy wise then go with the 257 Ocelot. Can run most 25 cal. bullets at mag length, light recoil, and easy to form brass (same for mongoose - brass wise). Just in case you haven't seen them yet......

I have looked at them briefly but I must admit I haven't looked very closely at the numbers, I'll check them out for sure! Thanks!

Is the 28 GPC going to become a reality?  I have a ton of 7mm handgun bullets and need an economical 7mm for the AR.
