Home Forums Reloading Big Game Rifles Favorite 62gr TTSX loads out of 223 and 223AI

They were only 5 shot groups.. I suspect if larger samples, say 10+, the data would have evened out more (approx 35 fps per 0.5 gr increase in powder). I don't measure every charge, I use a RCBS Uniflow powder measure, but TAC generally meters really well.
