It was a good dead but I think most general sportsman shooters will read too much into it. For practical shooting a barrel will last way past 10k rounds, closer to 30.
They were shooting constantly over a day, rapid fire. That GREATLY increased barrel erosion.
I enjoyed the wrote up but couldn't help but think that it was worthless. Yes, brass cased ammo is better. Steel is (was?) cheaper and still worth it (6 malfs in 10k rounds was it?) wow, total shocker there guys.
If anything I think the test showed that bush master sucks.
TWO poorly assembled rifles out of the box? ****ing lame.
