im shooting benikke rotweil slugs right now. i found that my bps throws those pretty nice(it can shoot gruops of 3 all in one touching hole.) but the problem is that at 50 yds its 4" up and at 75yds its 8 inches up. my question is if i switched from a 2 3/4" 1 once slug to a 3" 1.50 once sluge will thye slug drop so it will be more acurate or will the extra 1/4 of gun powder make the 1.5 once slug still shoot high?
