The early rifles like my 1889 used the 7.5x53 cartridge with a paper patched bullet.
Running mine with the NOE bullet designed for the K31 I experience misfires as with light cast loads, the cases actually shrink a bit.
The original bullet was 211 gr and paper patched to .321 while the bore was .308.
So I have a huge long throat to deal with and cases that won't consistently headspace on the shoulder.
Suggestions welcome but I want to avoid paper patching.
