More added info on bullets:

Buffalo Arms now has no bullets in 33 WCF or .348 WCF-may not carry any beyond current out-of-stock.. If the situation continues to deteriorate, casting may be the partial answer.
Gunner got some 270 grain Hawks from me and believe he will like their performance.
Scouring the net may produce results for components and dies.

Cannot Recommend going for re-barreling to 35 caliber in search of bullets.
