he!!o, here are some of my loads using Vihtavuori N540 and N340 (reduced loads).
.303 British.
Cases: PPU.
Gun: Lee Enfield No5 Jungle Carbine Barrel: 18.5" Primers: Magtech Large Rifle.
Bullets: Hornady 174gr .312 Interlock Round Nose Soft Point. Lead 115gr .312 RNFP.
Powders: Vihtavuori N540 & N340.
Light crimp. Cases were a first reload, full-length resize.
CAUTION: Although the N540 loads are within Vihtavuori's published data for similar weight bullets, there is no telling how these loads will behave in your rifle given all the variables present in reloading, and this particular bullet is not listed. There is no published data for N340 with the .303 British and there are anecdotal reports of blow-ups using very small charges in large cases. USE AT YOUR OWN RISK. Neither the writer, enfield-rifles.com ,nor the staff of enfield-rifles.com assume any liability for any damage or injury resulting from use of this information.
For comparaison, factory PPU 174gr FMJ cartridges give 2332fps in my No5 rifle.
