Ya, dang all copper bullets. I'm glad that I am not doing as much shooting as I used to.
When I first started shooting Thor's I would go through a box of them in a couple of days.
On the ML shooting sabots, I won a CVA Accura last year with a scope and the bore is so tight I couldn't get a .500 Thor to even think of starting. But since it had a scope and not legal here in Colorado I loaded it up with some Barnes TEZ bullets and sabots and it is lights out to 250 yards, that is as far as I shot it.
Then I went out and shot my ML deer in Utah with it at a very long 50-70 yards.
