I found that H4831 and Ramshot Hunter worked better for me, check your twist too, you may be using to heavy of a bullet 1-8 is good for 140gr but if you have 1-9 you might want to try lighter, I think it took 10 different bullets for me to find the 1 that outshoots all others

if you want change you have to put in your 2 cents, you can't just sit on the sidelines and whine
