Going from 70 to 80 Grains of lose powder in a .45 cva optima with 1 in 28 twist useing horaday 200g sab.'s at 25-30 yds will this give me the same effect as what im used to or is that a big change.. i want to try it b-4 sat but i may not be able to get to the range all i want is a lil more knockdown pwr i tryed 100 in this ml n i think its too much it won't group .. n the load i showed you guys at the top is what i got stuck with after many different combos. I know alot of you guys are shootin 100 grains i just don't know why this par. ml don't like it .. and is there a advantage to a .50 vs a .45? i'm new at this and all the help i get will be greatly app. ;-)
