[QUOTE="LB, post: 35904, member: 2721"] two things, Amigo. How did you damage the muzzle; and why did the shop lap the bore? Is this a factory barrel? In my opinion, your brass life is unacceptable and it should be replaced and your load, in your gun, is probably too hot. Considering all the case prep work, I'd like to get at least six and more likely eight firings per case. Do you have associated signs, flattened or cratered primers? There is such a thing as barrel harmonics, though, and experimenting with the powder; all things being equal, will show varying degrees of accuracy. The conventional wisdom is that Magnum chamberings shoot better with a max load. My particular 300 Win opens up the group with max charges of IMR4350, but not H4831. As you know, each gun is different. BTW, your shop will survive any small criticism it receives here, in spite of concerns to the contrary. [img]images/icons/smile.gif[/img] Good luck, LB [/QUOTE]
