does LEE make moulds for Swedish Jarmann rifles
Greetings from Wallenius
In short: No.
When they get their Custom Mold Department up and running again they might be able to make one to order, but it will probably be cheaper and faster to order from someone like "Accurate Molds", who specializes in one-off custom molds. https://www.accuratemolds.com/
The closest thing off the LEE shelves is their .410" , 195 grain SWC pistol mold. It will do to fireform brass cases, but is a very poor excuse for a rifle bullet.
