RE: 150 grains of 777 in an CVA Optima Pro .45?
Randy Wakeman is certainly a very opinionated guy, but he lists at least 4 incidents with this type of rifle. Don't think he is lying about that. I have yet to hear of ONE incident with T/C, Knight, etc.
Just because your rifle is safe and has no problems, doesn't mean that the next lot off the line might not.
All I am saying is why not try 90-120 grains? If you get the same accuracy and performance on game, why spend the extra money on powder? I have a T/C Omega and have never even tried above 120 grains (black powder equivalent)because I see no need, for me personally.
