These FPB's loaded really easy. I was kind of concerned after reading some of the posts by other members about the tight bore on the CVA when they were trying the FPB's. The conical was easy to load, popped it under the muzzle and then it slid down real good with the range rod. Its a shame it was so cold out there or I would have had a lot more time with these things. And I wanted to see how the bore conditioner would do.
