Interesting, Black Prince. I've wondered about that combination myself, since I'm also a Bullseye shooter. I don't use bevel based bullets, but I'll have to get some from a buddy that does.
I'm also intrigued by your comment about using wheelweights. I have often wondered about that. I think the issue is that wheelweights work poorly in ROUND BALLS, but would work fine in BULLETS.
Consider this: wheelweights are not as elastic as pure lead, which means that when compressed, wheelweights don't spring back as much as lead. This is an issue in round balls, since the portion of the ball actually in contact with the barrel is a fraction of the surface area of the ball. The bullet has much more surface area, so the lack of elasticity would be made up by the large contact surfaces.
Also, the less elasticity of wheelweights means that the material is more easily "stripped off" rather than deformed, as pure lead. When the low surface area of round ball hits the rifling, pure lead will deform and "grip" the rifling. If necessary, pure lead can even swage up to grip the rifling. Wheelweight round balls, on the other hand, will strip instead of gripping the rifling, leading the barrel badly. In a conventional bullet, the larger bearing surface again makes up for the lack of elasticity. The larger bearing surface allows enough "grip" to prevent stripping the bullet.
I'm really intrigued by this idea, so I created a new thread with this as the topic. Please reply there, if anyone's interested.
Thanks,
