I recently acquired a .58 cal barrel with the following specs.
.580 bore
.012 groove depth
8 wide grooves/narrow lands-similar to Forsythe
1/70 twist.

Ordinarily my load recipe would include a .570 ball and .018 patch, at least for starters, but I'm thinking the very narrow lands/wide grooves, .012 depth may
require a bigger ball(.575?) and/or a thicker patch.

Comments will be appreciated.

That sounds like the two GM 58's that I made, 570 worked great in them, 110 gr. 2f and maybe alittle thicker patch.    Gary

My choice would be the .575" ball too Duane.

Yes - I'd use a .575" with a 10oz denim patch or ticking- either .020" top .022" thick.
