What do you all think the effective range of a 300 grain Swift A-frame factory load in a 460 S&W is on an illinois whitetail? I know the shooter must do his part and at 100 yards I?m getting around 2 inch groups with my encore pistol and scope currently. I can do better and am considering a trigger job to help accuracy a little bit. I shot hornady sst, xtp, handgun hunter as well as Barnes and swift today. Swift was hands down the most accurate for me. Thoughts?
