[QUOTE="dfanonymous, post: 2629583, member: 97050"] Barrel expansion from warming up. A good way to test is to let 10 minutes sit between each shot. That said, I wouldn’t do anything less then a 10 shot average. I never got the point of a 3 shot group. Thinner profile barrels you’ll notice more of this shift. This is all assuming you’re at 100y. Further than that, and it introduces more variables. [/QUOTE]
