Folks: I've been pondering whether or how to shoot father's RB rifle and carbine. Both are alleged ly chambered for a single live round I have that my dial claipers and poor eyes say is 43 Mauser. Neither has manufacturer marks (not anymore...) the rifle has some fragments of a patent date on the tang... My two trys at chamber casts were not useful... I found a half-full (12 of 20) box of 43 Mauser cartridges w/385 gr lead rn bullet, yesterday at a local shop. Made by Dominion; C-I-L. Besides the shoulder being a hair different from the original, they measure identically and fit (rb closes). What's the "poop" on DOMINION? 'Still in Canada? Blackpowder? I scanned the box and saved it in .pdf format; can I insert it in this posting? Besides Buffalo Arms and Old Western Scrounger are there other sources for loaded 43 Mauser (11.15 X 60R)...that have it in stock? Thanks, Geoff in DE
