Like Construtor said. It will shoot great. I broke in 4 xtremes. 2 with tubbs, 1 with iosso, one just started shooting it. I cleaned it every 10 or so rounds and it has smoothed out nicely. It shows a little more pressure with max loads. It's probably because the round count is still low. Last time I cleaned it it showed very little copper fowling. They get smoother and smother the more you shoot.
