TCR barrel in .357 dia?

[schuetzen]

Does anyone know if a TCR barrel (for TCR '83 or '87) that has .357 rifling that could be reamed out for a .357 Maximum?

I don't think I understand your question. Do you have a barrel with a .357 bore that does not have a chamber? If so, I don't see why you could not chamber it for that cartridge. The factory made TCR barrels in larger cartridges which would operate at equal or greater pressure. You would also need an extractor to fit the cartridge.

The only .357" rifling (bore ?), which could conceivably be "reamed out to .357 Maximum" would be one previously chambered to a smaller cartridge, like either .38 Special or .357 Rem mag - neither of which were a catalog offering in the TCR line of rifles.

Even IF the TCR WAS chambered to another .35 caliber (.357") cartridge, and AFAIK it wasn't, pretty much everything else's chamber is already larger than a .357 Max.

IOW, no.

An option is to take the monobloc from a current barrel, and have a new barrel fixed to it, in the caliber you want.  I don't know of any barrel houses doing this so it would have to be done at a 'smith's shop.
