Question about 450b pressures

[vz58]

Yugo trunnion bolt combinations have and are holding 308, 243, 8mm, 7.62x 39, 444 pressures. So the 450 should be good to go.

Your right I had forgotten about the carbine conversions, I will have to check a M1 mag.

Also I have plenty of the 223 ak mags and the slightly more curved ak74 mags. Also you can mill or by magwell adapters to use ar15 mags.

Not sure about the 45 but I once owned a M1 carbine made by Olimpic Arms that was factory chambered and barrel stamped for the 256 Win Mag. It was a strange animule.
