Have a Shaw barrel I bought from a fellow, 17 Remington. Not planning on being nice to it. 15.5 Hornady running around 4800 FPS shot well out to 200. Will see what it takes to “fry” it.
I bought 1-2 boxes of those for someday when I have a barrel. Won't be trying to fry but I do want to see what happens when a 4800-4900 fps bullet meets small rodents. I'm thinking mouse-size. I don't want to shoot enough of them to destroy a barrel, just enough for rare moments of amusement.
