[QUOTE="davkrat, post: 1065694, member: 6452"] I wouldn't assume that a higher impact means you're over pressure. I've shot 4 or 5 different bullets through the same gun on one target and they were thrown all over the place. No rhyme or reason heavies hitting high, lightweights flying off to one side.... In my 7mm Rem Mag shooting 150 grain ETips one grain less H1000 gets nearly identical velocity (within 50 fps) as Retumbo. The H1000 groups about 1 MOA low and 3 MOA to the left. Both shoot similar sized groups but there is no way I can simply swap loads without rezeroing. All has to do with harmonics and every bullet/powder/barrel combination is different. [/QUOTE]
