I’m setting up to reload for my S&W M&P15 Sport , 5.56. I have a couple pounds of H335 that I use for my .35 Remington. In my reloading stuff I found 1,000 Remington 6 ½ (small rifle) primers. I was wondering if I could use those for loading 55 grain fmj over the H335. I checked my loading manuals. Speer #10 says magnum primers. Lee #2 says small rifle primers. Lyman #49 says Remington 7 ½ (small rifle magnum). The Hodgdon website does not specify. Can the Remington 6 ½ primers be used for my application?
