Question for the gunsmiths: How difficult is it to chamber a 9.3 x 62 into a .375 barrel and open up the resizing die to accommodate?

1. Easy. If you have a 375 Neck and throater.
2. Easy, if you anneal the die first. And you need a chucking reamer of the right diameter for the neck. Probably something like .385.

375 Scovill ?

I have a 375 scovill, and I made the reloading die by taking a Hornady 9.3x62R and using a carbide reamer to open up the neck. No annealing needed. Works perfectly.

The 375 scovill is a 9.3x62 opened up to .375. Most of the reamers are cut to use 30-06 brass instead of 9.3 brass. Easily rented reamer.

Carbide; that's cheating.
Consider a 376 Steyr; no alterations required.

Cheating, maybe. $20 for a hornady sizer, and $10 for a cheap 10mm carbide reamer and I had a custom sizer die.

That was a joke.

I have had little success annealing sizing dies. They seem to meander a lot in the process!
