I just picked up a Sako Vixen in 222 Rem mag. Can this be rechambered to .223 cal?

Thank You

.222 Magnum is already longer in case length and headspace dimensions, you can't ream a big hole smaller.

I guess the barrel could be set back enough to allow it, with the shank extended and the shoulder moved, but that would run up a big gunsmithing bill.

Brass is available.

Will .222 Mag rounds fit into your magazine? Many years ago I had a Sako short action fitted with Douglas Premium barrel and chambered for .222 Rem Mag. The gun shot great, extremely small groups, but the bullets had to be seated very deep to fit into the short magazine. I had a local gunsmith open up the front of magazine so I could fit 3 rounds in it with longer seated bullets. The gun worked fine but was limited to 3 round magazine capacity for my handloads.

Just a dinosaurs opinion but you already have a gun better than the 223, only reason to change would be to economize on ammo. Better to buy a 223 if that is your objective. Personally I would rather have the 222 Mag.

I would think that there might be some collector interest in the rifle in that caliber. it would be easier to trade and get the 223 that you really want. those rifles would really shoot good.

I have a 223 Cooper 21 and a custom Sako 222 Mag. I setup my neck-sizer to siz every bit of the neck of my Mag, and I don't need to change anything to necksize plenty of my 223 necks to do the job. Rem 222 Mag brass is readily available from Midway and/or Huntington. Going to all that trouble and expense is hard to justify when the results are so similar.

To rechamber the 222 Mag for 223 Rem, you will need to set the barrel back and recut the chamber. Fairy simple operation. Whether you would want to go to all the trouble is a different issue entirely.

Why would you want to? The 222 is probably the sweetest 22 ever made.
