Wrangler5, I'd venture a guess that your re-reamed 30-1 may be extra accurate BECAUSE it was re-reamed and has a better matched and fitted set of chambers. There was nothing inherently wrong with the Model 30 design, and with a little tweaking it becomes great! I've toyed with performing the same mod on my niece's 30-1, but it does so well and she lies it so much just the way it is, I figure "why bother?"
