Re: touch hole liner
You do not want the liner to protrude into the barrel at all; neither should it be recessed relative to the barrel interior. In either case (if it is not flush to the interior of the barrel), it with be a collection point for gunk and cause untold issues relative to maintance, performance and be the source of all kinds of issues. Not the least of which will be the propensity of cleaning jags, patches and solvents to get caught on it. Lastly, it protrudes into the barrel there is a real possibility that it will interferes with actually ramming the charge consistently. Maybe even cause a gap in the powder - which would be bad.
