[QUOTE="Michael Eichele, post: 349498, member: 1007"] I have seen the effects of the 'cold bore' shot on both my cut and button barrels. This is a problem you can find with nearly every barrel. My opinion is that it has more to do with a reaction of a cold peice of steel when heated very rapidly than from stress issues. Cut, buttoned, a cold bore is a cold bore. To me, a cold bore shot doesnt always meen a 1st round. I dont see fliers on round number one in the summer or when my barrel is 70 degrees from sitting in my warm truck. I do see it when my barrel is very cold. Ussually well under the 32 degree mark. Some have been more sensitive than others but I have seen all of my barrels do this. Learn where your 1st shot goes and at what temprature this starts to manifest. When hunting in fair weather, dont worry about it. It is hard to say but does sound consistent with throat and bore wear. Both my RUM's did it. One was slower to show it than the other but with both, I had to readjust my loads more than once. One was every 20 rounds after the first 70 till I hit 200-250 rounds and every 50-100 rounds after that. I gave up on it after 500ish. The other was a much slower proccess and still shoots very well after 1100 rounds through it albiet it is at a reduced load. 3250 with the 178 is all I can get out of her without pressure signs.
