Home Forums Hunting & Shooting Gunsmithing Re-chambering Combo Gun 222 to 223?

I'm considering having a Valmet BBF re-chambered from 222Rem to 223. Since there's no way to set the barrel back, is this too risky?


This gun

The most likely issue is for the diameter at the shoulder to be slightly large on the original 222 chamber.This means there may be a ridge left when the chamber is cut for the 223. One can take a careful measurement as close to the shoulder as he can get with a hole mike or even a telescoping gauge and find out ahead of time if the chamber will clean up. Once this is ascertained, it only remains to establish the correct ser-up to do the job. GD

Why? 222 ammo is readily available, while not as cheap as 223, you will find that the 222 is adequate and very accurate. Plus, the twist rate is slower than most 223's meaning you would be limited to 55 gr or less bullets.

Most likely, they twist rate will be too slow and you will and up hand loading lighter bullet weights. If you're going to do that, you might as well load 222's.
