A freind of mine just gave me 50 375grain 416 dia. cast bullets to try in my little project, the 416 bear. Thats a nanget M44 rebarreled to 416 cal. and simply a 7.62x 54R opened up ( darn near straight cased). I was considering starting with 52 grains of IMR 4895 as a starting load but I'm not sure if thats a good place to start. Any thoughts?
