Thread: Moulds/sizers for 577/450 Martini Henry

Lee make 457 moulds that seem to work fine as cast in my 2 martinis. Buy some from shooter nz and try them before committing and yes the original rounds were paper patched and the bore has an enormous tapered leade. Paper patching is quite easy there are plenty of utube videos on it but a bit tricky on a grooved bullet,
