S.E. Georgia? What city?

I was ran out of Glynn County on a rail many years ago. Got away just in time to miss the tar and feathers.

Only correct way is to use a reamer. Likely need to adjust headspace anyway when the barrels are installed on a different action.

This is a lathe job: Set the barrel up in the lathe, dial in the bore correctly, measure the receiver for headspace and barrel shoulder dimensions, then correct the barrel as required, and ream with a standard reamer.

What cartridges??

selling one of my old tight neck varmint barrels. new owner wants to use factory ammo-not a reloader.
how can i enlarge neck to factory size,short of buying or renting a reamer.

thank you
