I went to the range this AM with some test loads (Reloader 22) and found that 53.5 grains /110 Nosler Accubond/ CCI 200 / Win brass. shot 1/2".
I have 3 loads that do that one with 100 gr Sierra / H4831/ CCI 200 and the other is a 115 Nosler BT/ H4831/CCI 250 primer. This seems to follow the same pattern as other 25s I have had. They seem to function at one specfic powder charge and a 1/2 grain either way just does not work.
I called Nosler and talked to their service rep Mike (nice guy) he told me their test load max. was 53.5 gr of Reloader 22 / He also said it clocked out at 3197 FPS.
