Kalabaddon, Please forgive me if I sounded short. I’m an Engineer with minimal social skills. All of your points are valid. If you’re listing modern(ish) levers with box mags, don’t leave out the Winchester 88.

Stockwell, You might have to re-barrel. Barrel blanks are reasonably priced. The gunsmithery for fitting will probably be the bigger bite. Plus bluing. The old barrel would probably have $80+ scrap value.

One of the older hands here should be able to answer your question about heavy barrel from the factory.
