6.5's and 7's.

I have two of LEE's custom 6.5mm cruise missile molds from Midsouth. I had a machinist pal cut one down two grooves, resulting in a PB 140gr. cast boolit. For the big guy I got a Lyman .266 sizer die for the Lyman lubrisizer cuz LEE doesn't make a push-through in that size for some reason, and had the same pal polish it a bit inside (to .268") because it was rough enough to jam the cast LEE boolits TIGHT requiring disassembly to get them out all deformed. It will now seat and size Hornady 7mm gas checks onto the 6.5mm cruise missile castings, plain or PC'd, and the PC'd PB's slip through effortlessly. FYI. YMMV.

.266....custom order from Lee

Lee doesn’t seem to like the 6.5mm caliber. Probably because most people have a hard time getting lead boolits this size to perform well. I know I am, but I’m still working on it.
