I put together a 25 wsm some time back, its an ok caliber but has some quirks. With mine I would get a load worked up, great accuracy and velocities, next time I would go out I would get pressure signs. RL25,RL22, H4831SC, H1000, VV165, VV170, RS Magnum.....used many powders. RETUMBO was by far the best I used. I killed the bull in my avatar with my 25 wsm, 115 partition worked great.

To get away from the pressure problems I ended up using loads that were not much faster than my 25-06. Barrel life is short. I used all 100 and 115 gr bullets. Using 85 grainers barrel life will be even shorter. Barrel was a pacnor with polygonal rifling. I since turned that rifle into a 223AI. If i do a 25 caliber wildcat again it will be the 257 AI.
