  1. This is a Paul Mathews ... review by David on 6/12/2017

    This is a Paul Mathews designed bullet. It is of \"bore rider\" design, which means the front driving bands are smaller diameter than the rear bands. This allows the bullet to be seated further out of the case to make more room for powder.It is a great BPCR design and carries a lot of lube. On a good day, I\'ve gone ten shots without fouling out with this bullet. Most days, I only make it to eight shots before fouling takes its toll on accuracy. That\'s still very good with no wiping or blow-tubing.Unfortunately, not every Lyman mold in this design yields completely cylindrical bullets. I have two molds of this design and one of them makes bullets that are more elliptical than cylindrical. Thus, only four stars. Wonderful bullet design, less than impressive mold.
