Thanks, I have this notion to try and have a series of barrels chambered in factory cartridges that are based on the 30-30 case. Starting with the 219 Zipper, then 25-35, factory 30-30 barrel, then maybe 375 Win, 32 Win Special, and 7-30 waters. May look for a 38-55 barrel as well, but would rather have one for 375 Win. Past that, I haven't made any other decisions or plans yet. I do have a couple of 26" 7-08 barrels that I could get as well, so 7-30 may rank higher on the list. Thanks, Billy
