[QUOTE="swampratt, post: 3566127, member: 15054"] Nice video again as always. Now something I noticed when shooting for groups is my barrels have a happy spot in the temperature department. My older heavy barrel Savage .308 started grouping tighter when it reached 85 degrees and began opening up when it got about 20 degrees hotter. Next time you are shooting groups with different loads with different brass or bullets or charge weights do a round robin shooting. I have multiple points of aim on a piece of paper and shoot 1 Winchester load and then pick another point of aim and shoot a PPU Load. Then back to an Winchester and so on. This will eliminate favoritism to a warm barrel or cold barrel. [/QUOTE]
