Clark,

North Fork does not make bullets above .474".

GS Custom makes solids for the .577 NE.

You are pretty much limited to Woodleigh and GS Custom.

500nitro,

The Woodleigh solids I have are tapered in the nose area only; not in the shank that touches the barrel. And they tend to generate more barrel heat and more fouling (subjective observation) than GS Custom, so I do not think that reducing bullet diameter by 0.001" solves the problem. If bullet size were reduced sufficiently to solve the problem, then blowby would be an issue.

Woodleigh are a good bullet, but the fact is that they have been technologically surpassed. That does not mean people should not use them. In fact I shot some Woodleighs just last week.
