Buffalo Arms has bullets in stock (not the Hornady).  Accuracy is so-so with these in a Carcano because they are a hair undersized.

Off topic a bit…   I had Lee make a custom bullet sizing die at 0.298” to feed my 7.35 Carcano.

It works for jacketed bullets with thin jackets.  On bullets with too thick of a jacket, they spring back too much.  On the right bullets, they spring back to 0.300”.  125 grain or 130 grain bullets designed for varmint shooting work better than bullets designed for deer sized game.
