Update

I modified my gas block to be adjustable. I started with lower end loads from above and adjusted until the rifle functioned. Everything seems to be happy now. 85G SGK don't seem to shoot as well...

Figured out, hopefully.

I did 3 things and shot some more this morning. All cases ejected and all but one fed properly. I tried the first load as a single in the mag and it even locked the bolt back. The rims look good,...

"Is this a new bolt and extractor, or did it come from a previously used rifle? Having the extractor come of makes it sound like it or it's springs are worn. I would say it isn't just an issue of gas...

The brass I am using is Speer 07. It has a military crimp and it was real consistent in weight. The rim isn't ripping off but it is leaving a burr when it jumps over it. You can see where a little...

lee case length gage

If you buy the 762x39 trimmer, I think you can touch the tip of the pilot on a grinder enough to shorten it to the correct length. Try it, not much lost if it won't shorten that much. You can trim...

Vertical stringing

I tried 4198 in mine (a little longer 300W) trying to get a little more velocity and maybe a little more gas to cycle my rifle gas port position AR. I did not get the velocities that I did with 1680.

I played with a little 1680. I ran out fire forming brass and have more on order. I was up to about 23G and started seeing pretty flat primers with the 125G noslers. I hope I can bump it up a...
