I have an older LK93 54 caliber that I installed the 209 primer kit in. On the end of the breech mechanism is a small thumb screw. I found that it must be adjusted past the little RED circle or the primer will not ignite. At the range I adjusted it out so it would ignite the 209 bit not pierce it. Is this all you do or is there a certain number of threads you must count as you back it out?
