That 310 grain lee, does it need a special lube or would their tumble lube work? Also do you have to gas check them for slower 44 magnum velocities?
I don't tumble lube but I'd say most likely no as it has only one deep grease groove and the profile doesn't fit most tumble lube bullets.Special lube?.. Not really as I've tried many but I'm strictly using
TAC 1 lube for rifle and pistol presently for many reasons listed below... eliminating the gas check would strictly be trial an error but these Lee 310's drop a consistent .430 which may be OK for reduced loads but you could always pan lube to find out.
