i did not know cleaning jag would get down into there
What I was/am suggesting is not a cleaning jag - it is a wire patch puller - it is small enough to go in the smaller breech cavity. If you attach a patch to that you can guide it down into the breech cavity and apply a layer of protectant that way.
Since you are a flintlock user, and I have know experiance there, I am assuming you are using real BP. All the years we have been told do not mixpetrol products withBP - I would then guess you use Bore Butter. I would suggest that you you might get some WonderLube patches to use in the breech plug if that area concerns you. WonderLube, an all natural product,drys and leaves a film coating and in the breech area that would help seal that area from the air.A lot of BP users even use it as a bore swab.
i cant see pushing bore butter into that area as it may contaminate the powder.
I agree, I would not put bore butter down into the breech cavity.
Just curious, most of us that use a precussion cap of some sort pop a couple of caps before we load for the real shot, do flint users do the same or are you just loading and shooting?
I think Cayugad mentiond a aerosol dry lube, is there something along that line that might help through the vent liner? Being a sub powder user a coating of oil in the breech hasn't bothered me because I knew I was going to shoot it out discharging caps.
Most important - in my mind - get it dry...
