Which if any rimmed military rounds IE 7.62x54R, 303 British, the two I can think of right off hand, match rim diameter with 45-70? In order to facilitate a referral job with out slot of work on the boltface
Location: 3 miles NW of Brownells retail store and they keep me broke!
I'm coming up blank! 45-70 has a .608 rim diameter, 762X54 has a .567 rim diameter and 303 Brit has a .505 rim diameter.
The 303 is close to the 444 Marlin with the rim being a bit thicker. I have made 410 shells out of the 303 Brit cases. However unless I'm missing something I think the 45-70 is all by itself.....I'll research a bit when I get done moving snow.
