1891 Argentine re-barrel caliber?
I would like to ask is if it is possible for the 1891 Action to be chambered for the 9.5x56 Mannlicher S.? Alias .375 NE.
The .375 NE cartridge is the very close to same length and rim diameter of the original 7.65x53 load and the pressure of the .375 load is listed lower @ 44,000psi where the 7.65x53 is recorded at 55,000+
Am I reading these figures right or am I overlooking something important here.
A larger case and lead but lower in pressure?
I know pressures range differently in different cases/bullets like a 38-55 and 45-70 are large loads but are smaller in pressure than other cartridges in their categories.
I am thinking of Cast bullets , haven't decided on a length or barrel profile/twist as yet, but am thinking of about a 260gr. GC bullet loaded on reformed 8mm Mauser brass.
Chime in if you have any advise or experience on this .
Disclaimer, I didn't not tear up an 1891 Rifle , I know purists do not like this, I "rescued" the action and bolt from a trade and added the other parts from "surplus retailers".
Thanks
Ron
