I did not want to hijack the thread on speed and long range so I figure I'd ask separately. The thread which is very interesting, and a "bit" over my head has me wondering about what I'm shooting, as far as projectile is. I don't have a stable of custom moulds, I only have a few off the shelf ones.
I have 2 Lyman moulds, #1 is a 457125 500 gr. round nose, the #2 would be a #457132 535gr. Postell. And the oldest mould is a LEE 459-500-3R which is a 500 gr. Pointed Round Nose. What can you tell me about these? I'd really appreciate some input, besides they are junk and start over.
