    I've finished my bolt action 50 and for testing I've been using a bushing and a 215m primmer. Just wondering if anyone does this or if the small primmers affect ignition time and groups. I have a 30" barrel and have been using us869 powder, would h50bmg be harder to lite as the case would be less full. I don't mind getting #35 primmers. Can anyone give me an idea in lbs what it takes to set off a #35 versus a 215m?
