I haven't really had many issues up to this point. Seems like the 264WM heats up the barrel a little faster than the others, including the 270WSM. I think it is still fine, but I am getting a third shot a little further out than I want. I may slow up with this one just a hair. It is planting the first two on top of one another and the third is going 3/4" out. Not a show stopper, but there is some room for improvement. Scotty
