.455 265 gr. Mk II hollow base mould
.455 265 grain Mk II hollow base mould blocks-will need Lee commercial (six cavity) handles-see under mould handles.
This bullet has large hollow base and nose from top groove is .590" long verses the Webley bullet of same weight with a .500" long nose. Some of the MK II versions were crimped .10 to .090" below case mouth for same OAL as the webley bullet. Special crimp die can be made to duplicate the in groove crimp feature-just ask.
