45 Raptor...A couple of years ago after my first AR15 in 223, I decided I wanted a big blaster for Iowa deer hunting. We have that straight case business here and 350 legend really wasn't on my radar yet. Everyone had a 450 BM and I kind of wanted a 50 Beowolf to go with my 6.5 Grendel. Somehow I learned that Arne Brennen was involved with the Grendel and had later developed a .45 AR to kind of "one up" the Beowolf. The thing I really liked about it was his position to not have any propriety control over others using his development. The other thing it was a rebated 460 case for a 308ar and not a AR15. That meant a little over 10,000 psi extra safety margin.
This round was designed to shoot bullets up to 390 grains. I got a 16" barrel from Satern here in Iowa and everything was fine. But now I have the casting bug and Its time to figure out how big a bullet I want to try first and see how well I can get this AR to group.
7.62x25...Shortly after getting a couple Tokarev pistols, I found a PPS43-C. (semi auto version of Russian tank troop machine gun) also chambered in the Tokarev round. Mags held 30 rounds, it was meant to be a machine gun, and surpluss was getting hard to find. My solution was to learn how to cast. Lucky for me Starline was making new brass and my dad was a plumber with a lead pot. That casting thing was kind of fun so I got molds for all my pistols.
Wasn't long I got the AR bug back and the logical thing for me at the time was build a Tokarev AR. I found Ron Williams in Florida that was making barrels and mag adaptors for my PPS-43 mags and I was off to the races.
Pistol length gas system and 308 buffer, shoots like 22 mag.
So my question to CBA guys is, what should I try to get this AR shooting straighter? I have noticed 110 speer HP shoot 1/2 sized groups of my blaster cast loads. Not sure how much longer bullet I could use without pushing bullet back into the case a little.
Maybe a few of you have played with these rounds?
