I have had my best accuracy results over the years using Federal 210 LR primers. Many others have had equally satisfactory results with Rem 9-1/2's, CCI's, and even Winchester primers. For the cartridges you listed, I would NOT use Magnum primers, not even for the 7mm Rem Mag., unless you were using a very slow ball powder in it, like H870 or AA8700.....

Every .22/250 case I've ever seen uses a Large Rifle size (.210") primer, not a Small Rifle primer........

quote: ORIGINAL: FastShootingCarts "Small Rifle, Large Rifle, Magnum? Which one will best suit the calibers listed above."

ALL the cartridges you listed use size .210" (LR diametrer) primers. I don't even use magnums in the 7mm REM., unless for slow ball powders. I use the Federal 215 Magnum primer in the .416 Rigby....
