[QUOTE="MagnumManiac, post: 1030555, member: 10755"] Your chamber may be tighter than others, therefore the early pressure signs, not all rifles can take the book max, it is afterall only a GUIDE. I would be happy with my projected velocity with less powder and leave it at that, but if there are ANY excessive pressure signs, I would back off that load at least one grain. I have a 25-06 and a 300WM that have very tight chambers and reach max pressure below most manuals max loads, it happens. If my neck was that loose, I would only be skim cutting the necks, .006" clearance is right at my limit for good accuracy, wouldn't want anymore than that amount. Cheers. gun) [/QUOTE]
