Any advice would be appreciated on this.
First time up to batt, A4 buffer tube, 308 buffer, 308 coil spring, 18" mid length barrel (Classic Firearms), non-adjustable gas block, Brownell's 308 BCG.
About every 3-4 rounds with brass cased ammo (M80 and 168gr BTHP) I was getting a stove pipe that would jam between the next round and the roof of the upper, generally badly bending the round that was loading in to the chamber. Wolf had it happen once (maybe twice?) out of 20 rounds.
I figured reading other stuff that it was over gassed.
So, up next, I got an adjustable gas block and a Strike Industry flat spring (a bunch of other stuff, but that is the ONLY thing related to the gas or action).
Closed off the AGB, no cycling. Opened it progressively using Wolf ammo till it cycled and held the bolt back. Opened another quarter turn, locked it down. Ran a few rounds of brass case and wolf and good. Put the handguard back on. Ran a 10 round mag of Magtech M80. 2nd to last round stove piped and jammed up the final round from the magazine. Everything is ejecting to 3 o'clock.
I backed off the AGB a turn, failed to cycle fully, progressively opened it little by little. Got it functioning, 1/8th turn. Back to ejecting to 3 o'clock, but I did notice BEFORE that 1/8th turn, some of the wolf was ending up backwards in the receiver sitting on top of the empty magazine. The extra 1/8th turn seemed to get it to eject okay.
I ran about 15-18 more rounds of brass case and ran almost all fine. It failed to pick up a round after the first shot on a 4 round magazine. Seemed like that could have been failure to seat the magazine properly. It DID eject the 1st round clear to my 3 o'clock fine. Just failed to strip the next round. A mag slap, pull the bolt and fired the next 3 just fine.
So, lots of words, but I wanted to try to describe everything the best I can.
My next thought is maybe it is the ejector. Too strong of an ejector spring? Is that a thing? Options? Take it out and cut part of a coil off? Should I get a 2nd one and compare it to what is in there? If so suggestions in the best option for an AR-10?
I'd think if the bolt isn't coming back super fast or super hard, that if a case is ending up in the receiver backwards, that perhaps the ejector is slamming the case too hard.
The extractor does appear to be holding cases well.
Thanks!
