gryphon,
Sounds like your good to go. I've ordered an Adams & Bennett 35cal profiled barrel blank and am trying to work out what to do with it. The 358Norma is like a sirens call to me, but I have other projects to finish first. Damn it but the cheap blued S/H Rugers so prevalent a few years back seem to have dried up. I'd love a blued/walnut Ruger in 358Norma. You've picked a good 'smith and another I'd recommend with a reamer are TSE (MAB) in Qld. Tony built mine and a mates 458AccRel's, plus has another with him now and he does really good work. Pays to shop with them as well if using an MAB barrel, good price and fast turn around of under 6 weeks.
Cheers...
Con
