Taurus RPC 3 POS RATL-R (Initial test) & 45 Auto with Collar Firing in Raging Hunter 460.
Can conclude that the RPC only needs a lightened trigger pull weight and it will be good to go, and the 45 Auto Collars need a slight geometry tweak to aid in extraction after firing. The Liberty Defense Ammo did not blow the collars off after firing, but standard Armscor did.
