Booster MM Hole Size

Post by Patsy57 »

Hey guys so I have two booster assemblies one is marked BK so its a YUGO and the hole size is 12.87mm (Marked 13.5 on the side) and the other is unmarked and the hole size is 11.35mm

My question is what is the correct one for 8mm ammo?

Also I have a marked "47" on the side and S113-19154 and is the piece (Forget the name) that slides into the booster. My question on this is, it has a hole of 9.00mm is that for 8mm ammo?

I Want to make sure I use the right stuff in my WW2 MG42.

Thanks!

Most folks go with the thought that you use the largest size hole that will make your mg42 work. If you use the 12.87 and it runs fine then use it. If it jams a lot then downsize to the normal 11mm. But understand that the kick back will be harder and lead to faster wear on the weapon.
