![]() Sierra Reloading 300 Wsm Manual For SierraThis is for an A-Bolt so Im restricted to SAAMI COAL due to magazine. ![]() ![]() IMR4831 hard to get enough powder in there but it will work. Firearm Used: Win Model 70 Barrel Length 24 Cases: win Primer: WLRM RL 19 Start Load 61.7 grains Max load 70.1 RL 22 Start 63.0 Max 7l.0 IMR-4831 61.7 68.7 H4831SC 63.l 70.9 They show that you can get the highest velocity of 3100 ftsec with both RL-19 and RL-22. I never pushed the load because I was looking for accuracy, so I settled on 67-69 grains of RL-19 in Norma cases and WLRM primers. This powder produced good accuracy and velocity in my 300WSMs. The Sierra manual gives the following for a few of the powders that you have listed.
