[QUOTE="7stw, post: 1407296, member: 22854"] Well, number one, is a two grain jump, is a big junp,I,and I'm assuming you aren't raising in thst interval. I mostly like to shoot while its cool, and allow a temp swing, that during hunting season, I'm not going to get a point of impact change. If you develope a load at , let's say fifty degrees, then go shoot ing at 90 degrees, I can guarantee poi, change. Particularly, if it iis a non temp stable powder. R22, will do just that, 7828, will to, if I remember right. R25, seemed to be not AS, bad, except at the extremes. So, the answer to you question, is yes, temp swings will blow primers, and give stiff bolts, and raising the charge in too large an interval will also. Easy does it! [/QUOTE]
