Martini Henry Mk IV bullet casting
I've just got a Mk IV MH from IMA, and want to get into the whole 9 yards of reloading for it. I already reload in various (nitro) calibres & also cast for my 2 BP pistols, so I know the basic mechanics. BPCR is a new arena for me.
But I'm a bit puzzled about casting for the MH Mk IV. I'vre read a number of threads saying to cast .457 & paper-patch up to .468. But a mate has said I ought to cast .468 & not patch it. I'm not looking for amazing accuracy, just average performance.
As far as I can see the advantages of each are -
.457 patched - the patch helps reduces BP & lead fouling (???)
.468 - you don't have to patch.
Anyone care to give an insight into what they do ? I'd like to balance this one out. Also, recommendations for a mold ? I've looked at the .468 480gr RCBS mold & a .457 408gr LEE mold, what are you guys using ? I expect there to be more than 1 "correct" answer. 
Thanks in advance for the feedback.
