[QUOTE="RCMSTER, post: 1970651, member: 54689"] So I was out shooting my Ruger no 1, in 25-06. Trying to find an acceptable load with 100 gr swift a-frames. I have a good load with norma 100 gr soft points and 56.5 gr of accurate mag-pro. Last 3 shot groups have averaged 3/4" @ 100, and the rifle is sighted in @ 2" high at that distance. Average velocity according to labradar is 3111 fps, with an SD of 13.8. Tonight, I load up 4 rounds with 55.5 gr of R-26. 3 of 4 shots were at slightly less than 5/8" @ 100. Average velocity by labradar was 3206 fps, with an SD of 18.7. But here's where I'm bewildered. POI of the swift a-frame was 5" south of the same grain norma bullet, while leaving the muzzle a full hundred fps faster. Anybody able to explain to me how this is? Thanks in advance for theories.
