Sorry to ask, but I lost my data I had written down for my buddys 300 wsm. Just need starting and max charge weight, and fill capacity for the max charge. Thanks.

Ok, after some scratching on my head I think it was around 63.0gr to start and around 67.5gr max. Does this sound about right? I know work up slow and look for pressure signs. More or less, just needed a place to start, and an idea of where the end might be.

Open to comments about this set up, RE22 and a 185gr Berger.

I have not used RL-22 to load 185 grain Bergers, but from looking at the Alliant web site your starting and max loads look ok. Alliant shows max for a 180 grain Speer bullet at 68.0 grains.

I have had very good success using IMR-7828 and 185 Bergers. I achieved just short of 3000 ft/sec and very good accuracy with my load. I have only shot it at targets.

IMR 7828ssc here too. I load it with Berger 210s and 230's in the 300 WSM. 210s run right around 2850 fps, and the 230s run around 2700.
