I looked around the site to answer this first, but I'm too dumb to find it.

I want to shoot a few 1000 rounds of Portugese 7.62 either this evening, or tomorrow.

I pulled the projos from 3 rounds, dumped the powder, and reseated the projos. I opened the headspace one click at a time until my 1919 would close on one of these dummy rounds.

Am I good to go, or do I open it up 1-2-3 more clicks?


Thanks!!!

Im no expert but have headpsaced mine for shooting a few times and have had no problems with the way I do it, just like the tutorial says, I dont use rounds , dummy or live just the barrel and bolt. I run the barrel all the way in and pull the charging handle back about half way and let it shoot forward, which it wont lock up and I can still see the barrel, I then run it out 1 click at a time until it locks up. then I go 2 more past that, after that I take it and shoot it, if it has problems with feeding Ill run it out or in a few clicks till I find what it likes for that ammo. I hope this helps and is right, but Im just a beginner when it comes to these hence my above post about how these things work anyway.

If you want to avoid blowing up your gun, just follow the "parts still inside the gun" method listed below. It's very simple and fool-proof as long as you are using a GI barrel and quality ammo. DO NOT USE A CARTRIDGE OR DUMMY ROUND WITH THIS HEADSPACING METHOD. THE CHAMBER SHOULD BE EMPTY!

The official head-space method relies on the barrel and ammo being in spec (it will be w/ GI barrels). If your barrel is after-market and bad quality (chamber depth relation to breech face must be exact), or you're using really crappy out-of-spec ammo, only then should you vary from the below procedure. If you decide to use an alternate head-space method from what is itemized in the below field training manual, you better know what you're doing or you'll likely blow-up your gun.

I went two clicks open beyond lockup as a starting point. I'm headed to the range in about an hour, I'll let you know how everything went!

BTW, I LOVE having stuff at the range that causes all the elmer fudds to stop and take notice! First it was 2 silencers, then a Serbu BFG .50 cal, and now this 1919 with a crankfire unit!!!

My next project is a semi M2 HB!
