Here are some dimensions. Cheapo, followed by Mitu. Cheapo goes to 3 numerals, Mitu to 4. I didn't bother to check either against my gauge blocks, because for the purpose, it doesn't matter.
Rim diameter: .724; .723.
Base diameter: .656; .655.
Diameter @ 2": .645; .643.
For reamer: .727, .659, .647.
Base to mouth, .006 tpi.
From mouth to pilot, 10 - 20 degree taper for forcing cone.
Pilot: bore diameter, less .001.
That would make a working reamer.
Barrel purchase, plus reamer, plus threading, chambering and fitting, $600?
Can't see that making any sense.
Scrapper Snider barrel, reamed smooth, chamber left as is, $50 for the reamer. That is practical.
I've never reamed a Snider barrel smooth, but I have reamed ml shotgun barrels for sleeving. No big deal. Have a couple of horribles on hand, should give it a try.
