scoring large calibers

[bross]

Does anyone know of a source for scoring gauges, either plug type or overlays, for calibers larger than .45"? I can easily get .177 through .45, but the big guys seem scarce. Even find something for shotgun slug sizes would be helpful.

Thanks for the help.

BCBPA at one time had transparent plastic overlays for scoring but I don't know if they still have any or not. I am pretty sure they have a web page
