I remember seeing an awesome overhead graphic explaining where the ejection is and what is ideal and what causes non-ideal ejection based on where the casings are going. Anyone know where I can find a copy of that?

Thanks,

That chart is the devil.

If your rifle is working, leave it alone. Once you start down the path of trying to solve a "issue" with the perfect ejection angle, money will disappear from your pockets.

Parts wear, ammo, environment, shooter's hold on the weapon, are all things that can effect where your brass ends up.

Don't let the chart rule you.

How far should casings be ejecting from the gun? Installed a new extractor spring with rubber bumper (no o ring) and some of them are just barely hopping out of the ejection port- never seen this before!

if some are just falling out that's not good ejection.

I almost hate to give this response again but I had one doing that because the bolt had too much rearward travel and the shells were dancing in the ejection port.

How far does your bolt go back when you pull it all the way back?

If the bolt will lock back on the bolt catch after the last round out, then the stoke is fine.

With a correct stroke, then the problem is easly reqonized.

Start by pulling all the way back on the charging handle and confrim that the face of the bolt stops about 1/4 to 3/8" in front of the back edge of the ejection port.

Next, pull the B/C and with the bolt in hand, cam a spent case off the extractor and pivot the ejector in the bolt a few time. The ejector should not be binding up in the bolt face channel for it, but should be under good spring tension.

Next look at the relief rim section of the extractor under the claw. The bottom of that channel should be flush with the recesses of the bolt, and now below it

Now get the spent case out again, and cam the ejector all the way in using the extractor, and now let go of the spent case so the ejector fires full strength back out. The spent case should have come off the bolt with some authory, and if the spent case is still on the bolt, then may have a problem with diameter of the bolt face recesses.

Lastly, could be as simple at the rifle slightly over gasses. the chamber not cleaned correctly, the wrong cleaning and lubing solvents used, with the spent case being dropped from the bolt face as the rifle goes to unlock. To check to see if this is the problem, just install a #60 O ring around the outside of the extractor spring before putting the extractor back in before a bit of live fire.



As for if the bolt is not locking back on the last round out of the mag (rifle short stroking), then we can start going over that instead.
