[QUOTE="rscott5028, post: 513149, member: 24624"] I'm surprised nobody ever replied... I am completely unfamiliar with 338 anything. But, I'm thinking about building one. So, I was hoping to learn something. I see no point in altering factory loads. They're great to establish a baseline. But if you handload, you might as well build your ammo from the ground up. It also sounds like you've got a lot of variations going. Either you're shooting a lot or perhaps not spending enough time with one set of components? Are you using the Fed gm215m primers? How many rounds have you fired over 2 yrs? And, how's the barrel life? Might the throat be erroding forward? Do you need to check your COAL again and adjust your seating depth? In any case, 3/4" @ 100yds with a cannon like that will handle most people's hunting requirements. If it was me, I'd take one of the better loads and start fine tuning seating depth while paying close attention to brass prep. ..also, measure, weigh, and sort everything. Let us know how it turns out. -- richard [/QUOTE]
