[QUOTE="BrentM, post: 1092877, member: 61747"] Hmmmm..... curious, what gauge was used to set the head space? Have you measured the head space of a fired case? What did the smith cut the throat to? It seems strange you can get that much pressure without bolt lift issues. Any time I get pressure signs like flat and cratered primers I usually start to see ejector marks. As soon I see ejector marks I start getting heavy lift. For me, ejector marks (brass flow) is the end of testing, I back off at that point. I think as long as you have consistency in the powder charge, neck tension, seating depth, and of course shooter controls you have not yet found the sweet spot you are looking for. Perhaps go back to a ladder test of a powder range you feel is working well and do it at 400 to 500 yards. As soon as you get that low vertical range then shoot a couple of groups at that distance. Here is what the retumbo loads did, for reference against the h1000. I see the nodes I want to work with in both powders, but I notice retumbo has a much larger spread. Not that is an issue, it just seems H1000 has more potential for tuning. The 2 powders did the same thing in my 243. [/QUOTE]
