Rolland:
This rifle shoots to the sights with 41gr AR2209 (=H4350) beneath a 215gr RN bullet.
Muzzle velocity is in the order of 2050 fps from memory.

The Martini Enfield A&N sporter in my collection prefers 40gr AR2208 (=Varget) with the 215gr bullet.
In the Lee Speed pictured above, that load produces a few more fps but shoots 6" high at 100yds.

Mickey:
the photos are now archived on NE.com, so they should be permanent.
Apologies for the pink velour background material, dusty canvas from now on!
