If you want it done right....
I think that e-bay $60 take-off bbl I bought might be one of those "others". There is a "loose spot' midway down the bbl when I was Dyna-bore- teking it.
Gotta play with it tho- like I said, I can hang that 17" "Stub" that has worked so well over the years back on it before season if I have to.
I'm re-conditiuoning a lathe I put into grease-balls about 35 years ago. Life happens .. it ain't like I'm out anything, if I can remember how to run the thing...
. Almost there- just chipping the 50 year old grease out of the worm drive...
Always have a fall-back when dinking.... Besides, I liked that "carbine" configuration even if bit noisy. My wife knocked a yearling caribou bull kicking at 200 yards with it 3 years ago, using reduced recoil 30-06 ammo. Can't knock it.
