Fellas just asking for a friend looking at these calibres in a modern lever gun. He wants to shoot 200-240 grain bullets at 1000-1250fps and was thinking of loading 44 special brass in a 44 mag lever. The question is whether there is any advantage to getting a 44-40 instead from an accuracy point of view? Or maybe just downloading 44 mag to start with. He will only be using light charges of moderately fast burners( nothing slower than unique). I think he figured maybe the 44 special will have less powder position variations being a smaller case, but then it has to make a jump to the rifling. Anything to really split this decision or is it all splitting hairs?
