Use the primers, save the boxes.
Im glad you posted this statement. I have 2K Remington 6 1/2. I was considering using them for .357 Mag loads. Was advised against it . But if they can run .221 pressure, Im sure there wont be an issue with .357 Mag
It might not be ideal, but I ran thousands of 6-1/2s through my M1 carbines and it is still my most accurate load with WC820 and 2400, consistently under 4" at 100yds which I consider pretty good for what it is. The 296 loads were a little behind, but not by much. Using 7-1/2s didn't produce quite as nice a group for me, but once again the difference wasn't huge.The Remington 6 1/2 is a really mild Small Rifle primer, use it in 22 Hornet, 218, Bee 25-20, 32-20 and the like. I use it in 221 Fireball and 222Rem too. Way under powered for 223 or 30 Carbine with H110 or WW 296! but does work well with ACC Blackout Subsonic 220 grain loads (H 4227)
