I was given a brick of Win. Mag. large rifle primers. I've never used them before, I never have loaded anything that called for them.I load for 220 Swift and 22-250. I figure if one reduces his loads a little, they should work shoot the same. Right or wrong? Give me some advice guys...Thanks

I have never used magnum primers in a cartridge that small, I use them in .270 all the time. I would drop my load 5%, and try them.

I just looked around on the net, found some guys that had good luck with mag primers and win 760 in 22-250
