All of this really astounds me. Warren Page had a 7 mm Mashburn in 1952 that would drive a 175 gr bullet at 3000+ within 65K pressures. His did then and mine does now. I have 2, one has a 1:8 twist barrel on it. The other a standard 1:9.5. Either will shoot/kill about any kind of game up to about 1200 lbs to as far as I what to try the shot.
Reinventing the wheel I guess, just because you can.
Ha. Go look up history on 285 okh. 7mm with long seated 180 western tool and copper….
