Re: .510 Gibbs & BMG bullets

In reply to:
What's the optimum twist for this barrel?
I am not sure what it is but for standard bullets I think that it is about 1:12.
But the twiet rate for heavy 50bmg bullets would proberly quite different then for standard 50 jeffery or 500 nitroexpress bullets which are 100 grains or more lighter!
