I've read some real good things about them and their accuracy. I think they are nothing more then a stripped down CVA Optima with perhaps a shorter barrel (I am not sure). And yes they have the BPI barrels. If that does not bother you, then that should not be a concern. Load it within reason and I am sure you should not have problems.

I have not read too many reports on the owners shooting powerbelts. I would think with a BPI barrel they should be a good powerbelt shooter, but again this is only information taken from reading other people's posts. I have no personal experience with the rifle.
