Just so were clear everyone...I wasn't advocating anybody do anything.
I simply posted a viewpoint different from what most people have posted on this vent liner subject for the 10 years or so I've been reading forums.
I keep very detailed notes on my PC about every one of my rifles / smoothbores...the dates I shoot them, # of shots, every activity that takes place with them, all sorts of stuff.
Three Flintlocks in particular that I've mainly shot year round for the poast 10 years average a couple dozen trips & cleaning session per year...which adds up to the vent liners being removed/cleaned/lubed/reinstalled about 250-300 times each over the past 10 years...and they're still just like new today.
I know a lot of folks were raised on the notion "don't remove the vent liner"...read it for years...newcomers usually fall right in line and perpetuate that approach...and that's fine.
But its worth noting that that approach isn't a "necessary requirement"...and to make it clear that doing something outside the box doesn't automatically make it wrong to do it...just sharing a different viewpoint.
When I start shooting / cleaning the new Virginia, I'll be removing the lock & liner every time using a flush tube kit and for me personally am not worried about it...my feeling is that I HOPE I live long enough to wear out a vent liner & seat...
