311316 GC size?

I am nearly in possession of a new to me, but very lightly used condition Lyman 311316 (according to the pics and seller's description). I found it on a local forum. For those that use this mould, what size GCs are you using? I plan to use it for my Browning 53 rifle in 32-20. I was planning to use Hornady checks, but wasn't sure if I should go with 30 or 32 cal size. Thanks for your input. Bill in MA

30 cal is what I use.

I figured as such, since its much closer to 30 cal vs 8mm, but wanted to defer to those that have the experience using this mould - Thanks again, Bill in MA
