Forgive me if I am in the wrong area. I recently purchased this rifle more for the cartridge than the rifle. I have multiple boxes of factory ammunition. I would rather shoot cast bullets at less velocity and less recoil. I purchased a Lyman mould #311-284DV. It throws a 220 grain gas check bullet. I have cast the bullets and have lubricated them, sized and added gas checks. It is decision time! I have fired reduced loads in my 303 British rifles with cast bullets but I would like some direction with the 30-40 Krag. I have on hand 2400 and SR4759 in my reloading supplies. Ideas would be appreciated. I will mostly be firing at 50 and 100 yards with open sights. I am 76 years of age and shoot with my long time friends who are similarly aged! David
