Thread: 300wsm primer choice

Evening all,

I have both 210 and 215 feds on hand 215 went swimmingly in my 7mmrm but in my saum and blaser mag I used 210 both to good effect any advise on which I should start with.im just trying to save some time and mucking around also a starting charge for 190gn weights and rl26. Lots of mixed reviews especially when googling the primer choice people are having good results with either . Berger has data for their 180s with rl26 so failing any first hand knowledge il drop down a gn and start from their. Cheers
