Seems pretty simple to me.
I would get a Spikes buffer, two O rings, KNS pins, and Nano lube!!!
Then report back!!
This is my experience as well. When I fire hotter ammunition, ejection moves forward. Weaker ammunition,ejection moves rearward.
Fouled ejector (deformed bolt shaving brass seized it in the tunnel) caused my ejection pattern to move the same direction as weaker ammunition--about 3-4 o-click.
When I pull my charging handle all the way to the rear, the bolt face moves behind the ejection port.
Without seeing it with a slow motion camera, I am assuming the the bolt is dragging the brass into the back of the ejection port.
It could be a combined issue with the ejector spring and maybe needing a heavier buffer (using an H buffer in 16" BCM Middy)
After shimming the receiver extension with a washer, ejection is normal.
One reason it bothered me was because I was unsure if the hefty dents in the brass would be ok for reloading.
No I did not have any malfunction issues either, but I just felt its not how its supposed to be.
Shortening the receiver extension would be the desirable solution, but I lack the tools to grind it. Maybe a quality receiver extension would help. Mine is unknown.
I am unsure if I will let it go or continue to tinker (It is a hobby after all, It is not a duty weapon, and I dont use it for HD)
This is just my experience, yours may be different.
When I brought this up in another thread the general consensus was to leave it alone...
Thats what I figured......
Yup, that's what we figured too......
On that note, do you work for Red Jacket firearms by any chance?
Shimming and grinding parts is entirely useless, and will increase the chances of serious issues...
If you are having actual issues, it would be one thing to replace the parts, but this is not shop class, so put down the grinder... Not only that, but the "issues" you are describing are simply not a real problem, and don't need to be tinkered with or "fixed" at all, much less in the manner you are describing.
:haha:
