you'd get along great with my retired buddy that likes to build... I obviously didn't see this soon enough to make suggestions, so... enjoy the 7.62 X 39
BTW... my buddy was bored with his 7.62, so he put a 9mm barrel on his 93, & chambered it for 9 X 39, built the reamer & dies... I've shot it a few times... to me, it's closest to a 35 Remington... shoots nice though
In life you either make dust or eat dust...
