I am shooting them into a steel bullet trap. There is nothing left of them after they hit the angle wall and bounce down into the sand trap. I think they do show some promise. I like the Goex 2f better but the next time out I am going to drop the powder charge a little and see what happens. Maybe take them down to 85 grains of powder.
I know what you're feeling with wanting a new barrel and yet you have a good shooter. I look at my rack and wonder what rifle I want to shoot today, and then kind of kid myself that there is no need for all of them, but I never bought them because I needed them..
You'd sure like a Green Mountain Barrel for that rifle...
