This isn't a complaint, it's an observation and I'm wondering if someone might have insight into what's happening;
I picked up a Century C308 with wood furniture just before Covid tore our lives apart. Decent price, $600.
Here's what I've noticed about the rifle in the past couple years- front sight post was off, I had to dial it all the way over to the right to get it accurate. Seems ok now, groups ok. Not an issue to me now.
Extraction:
Steel, Red Army and Tula. 100% with very strong ejection. These are the cheapest rds I have, and have been the majority of the ammo I shot. The gun loves it.
Brass- Armscor 308 (got it from Ammoman, in plastic bags, when they sold "loose ammo" on sale. Obviously we're not going to see this again anytime soon). Also, Korean surplus 7.62x51, from the 80's.
I'm getting a relatively high rate of failed extract/eject with these, maybe 2 in 20 (several a mag). Sometimes more, sometimes a full mag runs fine. I'm not ripping the case rim. I see the striations from the fluted chamber on the case, dark marks but not really noticeable to touch.
I have read the concern about steel making a dirty chamber due to gas blow-by, and brass then sticking. My extraction issue with brass does seem to be "sticky", like it barely comes out of the chamber and doesn't clear the ejection port before the bolt comes home again.
NOTE- I've tried cleaning the chamber thoroughly, and then going exclusively brass, to avoid this; it doesn't seem to help or hurt.
I can shoot steel all day, with a dirty gun, never a problem. If I didn't know the gun was a NATO design (with NATO using brass), I'd swear it was designed to run steel. You guys have any insights into this, what I might do to improve the brass function? Or, should I just stick to steel since it's cheaper anyway?
