Looking for a blank for a .44mag carbine project. Specs I want are ~1:20 twist, 18" long and 1.25" or larger OD at the chamber end (if it isn't constant OD). Where would I look for such a thing? I would prefer to buy from someone in Kanada, but that may not be an option. Plenty of barrel suppliers in the US but I couldn't find one that listed a .429" option.
Thanks,
Mark
