Does anyone have a first hand account of ammunition for deer sized game. When I bought my Ruger I bought 260 gr JHP because that was all the guy had at the time. I know all the major ammo co. make something for the 454 casull. What would be the most practical for deer out to 125 yds? I was leaning towards the 300 grain from either Winchester or Federal. Any help would be appreicated.
