West Central AR
45s .
There is an approved 45-70 rebated rim designed for the AR-10.
A guy got his whiskers all twisted when I described it as a 284 Win blown straight and sized in the 45-70 dies .......it lacks something like .002 at the head of being a perfect match ........ The WSM and it's parents the nonbelted mags (I can't remember now if it's H&H or Rigby) are just over the dia at the head for a rimless 45-70 . I'm sure there's a name for a 45 cal 416 or 375 that stuffed full of FFFg makes a 45-90 or 45-100 . The WSM would just be a 458 barrel reamed with a 45-70 to 2.10 . Also in a .451 barrel you can ream to 2.449 with a rimless 45 pistol reamer and use an 06' blown straight or basic and use 45-70 data .
