What is the best primer for my 300 WM?My first shoice would be 215M's,but those are pretty much impossible to get now.Right now I have quite a few CCI large magnum primers,but didn't know if there is a better choice out there based on availability.
As I stated in another thread, check out the newest edition of Handloader magazine. There is an extremely in-depth study of how each component, when isolated affects accuracy, with results of his tests. The tested all the major primer's in isolation and publishes his results.
