Tony, as always, I enjoy your replies and learn from them. As you know, there is a ton of precision reloading info out there in print and the internet.
My problem is that I’m stubborn, opinionated, hard headed and want to see results on paper. When I try something; I don’t know if it’s my shooting or the info that is the problem. Being a trained investigator, I strongly suspect my shooting. My solution is to ask questions of those who have “been there, done that, got the T-shirt” and shoot well enough to prove or disprove the info floating around.
