It is in the testing stages as of right now. I do believe that they have hit 2600 FPS with a ninety grain bullet and I believe that they have hit 2500 with a 110 grain bullet.
He has been getting a little direction from H at Arp. I do believe that barrels have been ordered and they are getting their die sizing near completion.
Should be a pretty good cat-low cost brass-pretty good selection of bullets-standard 5.56 bolts and mags.
What you have here gents, is yet another guy shamelessly plugging HIS PRODUCT while pretending to be somebody else.
It's too bad Mark from Mad Dog has left us, it was just starting to get fun.........
Kinda funny how he messed the name up in the title too
Ok, so wrong. He is not me. I am.
So, the .277 Wolverine is yes - based on a 5.56 parent case with the shoulder bumped back .20 and an overall case length of 39mm, or, 6.8x39.
I'm not going to get into the petty arguments y'all are having, but I registered and am posting to let you all know that he is not me, and I don't appreciate the accusation. Anyways, whether you care about it being a 6.8 or .277 bullet vs. a 6.5 or a 6 I don't care, but here's the numbers so far in a recap. Oh and to the guy that was disappointed that we had to do some tweaking here and there while developing a Wildcat has obviously never developed a Wildcat before.
So far we're getting 2690fps with a 90 grain TNT with no pressure signs at all. No cratered or flattened primers, no swipes, no case stretch. We have room to move so we'll cross 2700fps with no problem.
So far we're getting 2500fps with a 110 grain Sierra Pro Hunter, no cratered or flattened primers, no swipes, no case stretch. We have room to move so we should be able to get to 2550fps without issue.
These are out of a 16" Pac-Nor barrel and sub-MOA all day. The powders we are testing are those between typical 6.8SPC and 300BLK powders due to the bore size, case capacity, bullet weight and surface area.
Please remember that unlike the 6.8x45 Kramer, this cartridge uses unmodified 5.56 maps, including Pmags even with it's pointy little front mag rib. The velocities of the Wolverine nip at the heels of the Kramer which nips at the heels of the SPC. Also, this cartridge is now in production and barrels, die sets, WFT's, Ammo Gauges and such are ordered/being ordered. Not full production obviously, as the first batches have been ordered and we're waiting for delivery. However, that's a lot closer than others.
So, there ya' have it. If you have any questions let me know and I'd be happy to respond.
Edit: If you like a 6.5 in a 5.56 case, check out the 6.5PCC. Vic is a good guy and doing well with it.
And Ezbagr, thanks for talking about the cartridge and I won't hold it against you that you got the name wrong ;-). All good.
