Lots of discussion going around about cast bevel base bullets. Why reloaders hate them. I would sum up their unfounded hate of them from the internet myth BS circled about them from know it all perpetrators. Here's a good one: the shorter bearing band length relates to twist and stability. Laughing my ass off on that one. It's the overall length of the bullet that determines the required twist not how much bearing band area contacts the rifling. The same person said that the reduced area because of the bevel may not leave enough bearing band area to full grip the rifling and stop it from skidding. He equated how leaving the gas check off a checked style bullet is basically the as the bevel base bullet and that they don't shoot. Duh...the reason it doesn't shoot isn't because it's like a bevel base bullet in the fact that the base isn't contacting anything. The only valid excuse is the one in lubing the bevel base bullets. Yes they are messier. There are ways to get around that. One which requires more work is to make a new ejection ram for the H/I die should you be using a luber/sizer type of machine for sizing and lubing. There are other tricks to get around it with those machines too. If you pan lube you're kind of shit out of luck. Bevel base bullets shoot just as well as flat base bullets.
Let the naysayer tell you how to get around the inconveniences of lubing bevel base bullets.
I'll venture to say you're talking about cast rifle bullets, right Ray? That question doesn't mean that there is a difference between shoot revolver gas check bullets and rifle gas check bullets without the checks. The poster that made that state about shooting the bullets without gas checks was referring strictly to handgun bullets.
If you use a Star Lubrisizer then the bevel base issue is irrelevant as the lube only gets injected into the precise area it is required or set to.
As to re-loading I much prefer bevel base bullets in that they go easier into the case and less of a flare is needed to the case mouth.
Are they less accurate? I knew many shots in 1500 Competitions who could shoot better than me with 148 grain BB-WC that I ever could with my 148 grain HB-WC that is for sure!
OTOH there is something about a fully filled out "just cast" flat base bullet that to the mind makes it seem as if it should perform better than the same with a bevel base.

Nice post and I couldn't agree with you more. I guess the flat base cast bullet looks "finished".
Originally posted by Idaho Sharpshooter: The people that own Laser-Cast state the reason they use bevel base bullet moulds in their machines are twofold.
1. They fall out of the moulds easily
2. They do not shave lead when seating the bullet.
I think I've shot about fifty-thousand over the last twenty years or so.
To answer your first two statements...DUH
What did you learn in shooting the little amount of them that you did? You addressed NONE of the issues brought forth in the original post.
A million years ago I believe the NRA did some accuracy studies on cast hand gun bullets and came to the conclusion that the flat based bullets gave slightly better accuracy in their test barrel than the bevel based bullets. I will have to dig around and see if I still have a copy. I believe the test bullets were all wad cutters. C.G.B.

People can argue about everything else, but this was my first thought too. So much so that I would expect the qualifier "...man they load so much easier than flat based bullets but..."
