Here's the back ground. Rifle sat for years unused. Started building suppressors (legal form 1.) Took the barrel off, had to cut the nut. Sent it off to get the barrel threaded. Installed with new nut and recoil lug from EABCO. Torqued to about 40ft lbs. Used Forster go/no go headspace gauges. Barrel lined up the same as when I took it off (no surprise there)
Load is random 308 cases, large rifle match primer, 10gr and 10.3gr trailboss, 180gr plated bullet (rainier wedge, terrible 300 blk bullet), seated as per the sierra load manual. 1090fps and 1120 fps.. gonna try 9.8gr for subsonic...
Out of 20 test rounds 6 failed to extract. Had to push them out with a rod. Came out easy. It's like the extractor claw never grabbed them. Tried briskly working the action with the fired case in the chamber, still wouldn't grab. I have the brass, but haven't inspected it yet and did not separate the failed cases from the good one.
Anyone got any ideas? Gonna tear apart the bolt tonight and reassemble. Did I mess up the head spacing? (I didn't pull the ejector spring like I should have when head spacing)
I believe this is all the pertinent information. TIA!
