hey just wondering if anyone loads for the 45-70 i just bought the marlin 1895lever action and i was just wondering what the heaviest bullet i can load for is because from what ive been reading in the lymans reloading book says 405 gr but in the lee loading manual it lists up to 500 gr so im a little confused i also realise max overal length must be 2.550" any help would be apreciated thanx
