Can anyone advise a load for me from a programme?
I want to replicate the Boer War - era .303 round, for use in my MLE, LEC, and ME rifles.
AFAIK, the Mk II .303 had a 215 grain jacketed bullet at a muzzle velocity of 1970 fps (quite similar to the Mk VI bullet (2060 fps)).
I am planning to buy 215 grain round nosed jacketed .303 bullets, and I need a recommended powder load which will give 1970 fps muzzle velocity from the Long Lee (barrel length: 30.2 inches).
I use the Vihtavuori powders, and have N140, N150 and N160 to hand. Lapua/Vihtavuori do not include a 215 grain .303 bullet in their load tables.
Can anyone assist?
