.30 Remington Brass Question

by Remington40x , SE PA, Thursday, August 30, 2012, 10:18 (4470 days ago)

Is the .30 Remington cartridge that's being chambered in the AR-15 platform the same cartridge dimensionally as the old .30 Remington that was chambered in the Remington Model 14 and 141 and some of the early Remington bolt actions?

I'm looking at a Model 141 and I wanted to be sure that the brass was reasonably available before I bought it.

Thanks.
