Build a .300 BLK powder die

Post by Maximumbob54 »

Direct from an email from Lee:

SE2398 357 Mag Die Body
SE2291 30 M1Expanding Plug

Follow those up with the lock ring, O ring, and funnel adapter and according to Lee you now have a .300 BLK powder through die that will expand the case mouth for lead bullets.

Guess I was close trying a .30 Luger insert and the die body but not quite close enough... :oops:
