Ranking loading variables to lower ES and SD

[Florida Wally]

I never believed primers made much difference until several yrs ago. 2 very accurate rifle I compete with all had ESs in the teens. By trying different primers I got them to 1, 4, and 5. It was the same primer, one I never used before. Only way you will know how primers will effect what your doing is to try them for yourself.

Thanks Jeff, but currently I’m lucky to have the primers I have. When they come back In stock, this is one of the things I was going to try.
