    45/70 is as follows (rule of thumb) rules are made to be broken though a
    1/22 Upto 420 maybe 450, 1/20 upto 500 1/18 500+
    Every twist rate I’ve tried will shoot lighter bullets also
    Have put 405gn through a 1/18 with good accuracy
    Not sure about 44 mag though I wouldn’t think it would be that far different

    Greenhills formula (think that's the correct spelling) will give you the right twist rate for weight. Just remember 44 mag is actually 41 caliber not .44

    Actually bullet diameter is .429" for copper and .430" for lead
