How do you coat a barrel that you can only access from the muzzle?
You put it in from the barrel side and run it down - I did it to my Lyman GPR and WOW !
What i did was to make sure it was "wet" with a damp mop, and worked it back and forth from the chamber on up, then I did it again but to make sure it was damp I poured a bit more down the bore onto the mop when it was at the bottom of the barrel, then I worked it up the bore again.
With my GPR I used to get a hard 3rd shot seated without swabbing, #4 was just plain dangerous.
Now that pattern occurs at the 8th shot - in fact if I leave the cap on after firing and seat the ball too fast sometimes it will move the bullet up the bore from the air pressure. Pretty wild.
I just cleaned all my shotgun barrels so I can coat them as well - some of the duck hunters found out that you get better patterns when the wads aren't getting yanked by fouling. If it's anything like my experience with my GPR ... I'm all over it.
