Yall are obviously way more knowledgeable about load development than I am, and I agree with what yall strive for on getting a high dollar rifle to shoot. I mean that's what standard you hold a custom rifle to. But what ever happened to shooting 3 or 5 shots at a hundred yards with various components? To me, I think a chronograph is the only way, my opinion. Same speed, same burn, same result. If your not happy with the speed, switch it up. Once all that's obtained at 100, back that up to 300, then 600, then whatever. Shoot at various Temps. Freezing to 100 degrees or so. Your cases and chronograph should tell all. And duh, the size of the group. Just an outsider looking in. By all means keep up the thread. Pretty good read.
