Loose as a goose

Hi, guys,

I've got an MK 2 from AC a while back. The bore is very good. I'm using RCBS, part #57923 with 12 gr. Blue Dot and a large pistol primer.
I get good results from this. About 3 inches at about 100 yards.
The cocking indicator pin hole extractor axis pin hole are very worn
Does anybody know if the worn pin holes in the action affect accuracy? Has anyone ever tried to find out what the full accuracy potential of a MH is? Would bushing the pin and lever holes improve accuracy?
You guys are the best.

Loose holes are fine, blue dot is not.

yeah just as double d said blue dot is not what you want to be using in these old guns blackpowder is what you want it burns alot slower then blue dot thats for sure
