View Full Version : Is this Triple Seven .45/70 load safe?

I put 50 grains *by weight* (not volume) of 777 into a .45/70 case with a 460 grain Cast Performance bullet (a rather long bullet). I am sure it is touching the powder with some compression. Want to fire in a newly made Winchester lever action. I know these are very strong and can handle over 45,000psi. I would think this load is in the 20,000psi range. Does anyone see a problem?

Triple Seven load data seems to want about 60 grains *by volume* for such a bullet, which would be about 42 grains by weight. So I am a little over that -- but then again, I am using a strong lever gun, not an old Trap Door.
