FWIW, bevel-base bullets are as easy (or hard) to cast as flat-base bullets. Bevel-base bullets are easy to insert into the case mouth, however, which is why most of our customers prefer them. We do have a few flat-base ones, based upon customer requests, and they sell like refrigerators to the Inuits.Every one of those CB bullets is a bevel based bullet, well almost every one. Bevel based bullets are never as accurate as a plain base bullet, but they ARE much easier to cast. Another thing, all but one has only one lube groove! I've never seen a 405 grain 45/70 bullet with ONLY ONE LUBE GROOVE!
I'd certainly pass on those bullets, for the previously stated reasons. Oh, the price is outrageous also!
