[QUOTE="william70d, post: 423419, member: 26698"] I know that there is a mystery about cold bore shots. Here is my experience and take on it. First off I am going to say that I have 3 rifles that I have experienced this on. The first is an dpms lr 308, a remington r5 308, and the current on on this thread the 7rum in a sendero. They all three have stainless barrels. After I do my break in period with the gun I use nothing but sweets 7.62 solvent and rem gun oil to clean it spotless. I use bore guides and only nylon bore brushes. After the gun is 100 percent clean. I use JB bore cleaner to make sure. After that I JB bore bright the ever living crap out of the gun. These three rifles will put the cold bore shot in the exact place as a round that is shot 20 rounds later. And remeber all three guns have factory barrels. I treat my other stainless guns with aftermarket barrels the same way. And they perform just as well if not better. Now here is the kicker...my chromoly steel barrels dont react the same. Actually I have 2 guns that wont group at all with a clean barrel. One of them takes 50 rounds before it will shoot 1 moa and the cold bore shot will be 1 in high and right from the rest at 100 yards. I have never figured this out why the stainless reacts so much different than the chromoly steel. And another thing while im on here....my polished factory stainless barrels will **** near shoot with my kriegers, harts, and shilens. I kind of got off topic here but........anyway [/QUOTE]
