imo, most barrels when heating up lose accuracy.
Maybe, but the Savage 25's were not going from like 1" groups to 1.5" or 2". After a couple shots they were off the paper. So much so that I thought maybe I'd forgotten how to shoot or there was some crazy wind happening that I couldn't feel. So I'd switch guns to my 22 hornet or 17hmr and both would be making tiny little groups. Might be a different issue than heat, it just seemed like I'd get a couple shots near where I was aiming, then suddenly it was shooting off the planet.
