Home Forums Reloading Big Game Rifles Need a good 300 WSM 165 grain load

I load for a friend's 300WSM, and like Bobcat, his rifle shoots little bitty groups with RL15. I've seen my buddy shoot a 1/2" group at 200 yards too. His bullet, though, is the 168gr Berger. I top out at 60.0gr with mag primers. He gets about 3,050fps out of a 24" tube.

After reading this thread I have decided to give the TSX's a try. I have one question generally speaking with this bullet what is a good starting OAL length

I've never been an expert on OAL and how it effects accuracy. But when loading for bolt guns with magazines, and especially that short action of the WMS's, I typically load them to the length to where they reliably feed down in the magazine well. If accuracy is good, I sight in. If you want to play later, I would load batches cinching down the die seater screw a turn or a turn and a half at a time and see what happens.
