https://preferredbarrelblanks.com/product/unturned-barrel-blanks/A very good friend of mine passed away 2 days ago... although my gun building days are behind me (couple hundred barrels)... been pondering a new caliber in his honor "9,3 Jimbo"... if any $ is ever made... 100% to his widow.
Basically a slightly faster and flatter version of .375 Raptor with a PO Ackley shoulder (maybe). FYI, are getting amazing results with the .375 Raptor... almost identical math to the .35 Whelen. 10 for 10 on 2 MOA steel at 400 with 270s.
But scarcity of everything is a huge "pause moment"... but still thinking.
