OK.. so that vent liner is like a backward nipple port of sorts. What happens if you do not change it out soon enough? I almost bought a Savage ML-10 last week. I was bidding on it but was beat. Which is fine by me.
Accuracy degrades, from my understanding.
Some report inline breechplugs also need to be replaced as they erode larger. I have many hundreds through my main Omega with no loss in accuracy so I've never personally seen it. Given the difference in propellants, it would not surprise me if this is why it's seen a lot sooner in a Savage. In a smokeless cartridge gun you never use brass hundreds of times to see any erosion but, similarly, if you get flash holes of differing sizes in your brass it will hurt accuracy.
