[QUOTE="tracybartlein, post: 2847766, member: 12065"] Use what works the best. In my 300PRC F Open gun. I originally started with Fed210M primers. I switched on a recommendation from Dave in the shop to try CCI200's as that's what he was using in his 300WM. My SD's and ES numbers dropped quite a bit going to the CCI200's. and I'm running 76gr of H1000 behind a 230gr bullet. A mag primer isn't necessarily the best. Yes there is the old rule of thumb of when you go over 60gr of powder to switch to a mag primer. Or depending on the type of powder or temp conditions you should be using a mag primer as well. Later, Frank Bartlein Barrels [/QUOTE]
