After talking with Lehigh a couple weeks ago, the new Mountaineer will be able to shoot all the BP subs on the market today right out of the box.

And Knight is also offering a breech plug for Extremes, Elites, and Long Range Hunters that will reliably shoot BH209 and other BP subs.

Knight Rifles is definitely headed in the right direction there first year back.
I forgot to mention the best Range Rod/Cleaning rod i have ever used by far.
