Which primer

[chuck m]

I recently acquired a 243 WSSM. I am unsure of the proper primer. Do I use a large rifle primer or a large rifle mag primer? I have seen both mentioned.

thanks in advance

Accuracy may vary with either but it's less than 50gr of powder. You certainly don't need a magnum primer for that. Noslers data says WLR primers. I note reloaders nest has data for each try the web sites below.

Good luck and shoot straight

Either will do but you don't need the mag. primer here unless you are using ball powder. My 25wssm is on wrl or 210 for most loads.

Thanks Guys, I'll stick with the large rifle primers.
