Slugging the barrel Questions
I have an older Shiloh Sharps. I am going to slug the barrel to find the exact size. Sounds simple but I read recently that some long-range barrels are choked down at the muzzle. Has anyone run into this? If that is true I assume I need to slug the barrel a short distance from the breech and then push it back out the breech.

I slugged mine from both ends. Push it in several inches from the breech and then push it back out the same way. Same trick with the muzzle. I'm not sure I could measure any choke with a hand held micrometer but I agree there is a minuet choke in the barrel.
Take your time, use plenty of oil or other lubricant.

Use pure lead for the 'slug'.

Re: Slugging the barrel Questions
Having been gun-smithing for 4 plus decades I'm trying to imagine how a broach or button or whatever would become smaller as it was drawn through a barrel and eventually resalt in a decreased barrel bore...??

Re: Slugging the barrel Questions
Hand lapping from the breech end will do it. My slightly choked at the muzzle barrels shoot quite well.
Usually, I used a pure lead slug about an inch or so long driven all the way through from the breech end to determine groove and bore diameter.
I wrap a thick cloth around the muzzle to catch the slug on exit.
Mostly satisfied curiosity as the rifle doesn't seem to care and as one of my hard holding shooting partners says, the barrel will make the bullet round before it leaves the muzzle.
I worry over bullet fit in fired case and to chamber more than anything else. Case separations are to be avoided.

Re: Slugging the barrel Questions
Anyone drop in certified plug gages to measure the lands and an inside micrometer for the groove depths?
