It has been 20 years since I reloaded lead bullets for use in a rifle (30-30 in a Winchester ‘94 for CAS long range and .303 British for use in a Martini Enfield carbine). I have now run out of those loads for the 30-30 (running a bit low for the .303 Brit too).

I have just cast up some 150 gn LRNFP projectiles and was looking at powder loads (can’t remember what I did last time other than I loaded down slightly). I have a powder but the loading tables only list jacketed bullets (31 gn Mulwex AR2208 minimum for 2172 fps).

I am looking for around 2000 fps so would a 1 1/2 drop in the powder charge we about right?
