You'll be into a gunsmith probably more dollars having him cut the barrel back at least the thread length then chambering and hoping the new chamber goes in dead nuts and takes out all of the old one.
A new McGowen blank is $165 and it gives a gunsmith a clean canvas so to speak, in my mind the new blank gives me better vibes
I'll second the above quote. Buy it cylindrical, not contoured. Chamber both ends (example; if you've got a 6.5mm x 284 and a .260 Rem or 6.5mm/06,,,,,, pic two). I think a better solution would be to have the barrel (on your custom) salt bath nitrided. Then just fire form in the original chamber. As mentioned in an earlier post, many times accuracy is very good
when fire forming most Ackleys. I've shot a .22/250 AI for years. Fire forming always gave me "minute of prairie dog". Besides, nitriding would cost less than a barrel blank from McGown, not to mention the threading and chambering costs.
