Rechambering the 25.06...Question

[Mykey]

I have an old Remington 25.06 thats been sitting in the safe for quite sometime thats not seeing any use and since i have another one i'm considering having the old one rechambered to either a 25.06 AI or a 257 Weatherby Mag just to have another toy to play with in a different caliber. I'm thinking more of going to the 257 since i have another 25.06 and the AI wouldn't really be a big difference to me. My question is this, if i rechamber to the 257 will the barrel have to be set back and would the bolt face and extractor have to be changed or modified for the magnum diameter? Also does anyone have a 257 Weatherby mag and if so what do you think of it? Thanks!

The .257 Wea mag is a very good round. I hav ebeen shooting one for about 25 years now, in a Mk V. I have taken everything from skunks and groundhogs to deer. Never had to put more than one round into any of them. You would not gain that much from the .25 AI over your 25-06. Another option is the .25 Gibbs, which is a ballistic twin of the .257 Wea. mag. The best way to describe the .25 Gibbs is an improved .25 AI.

No, the barrel would not have to be set back for the .257 Wea. Mag as it will clean up the 25-06 chamber. Yes, the bolt face would have to be opened up to the magnum bolt face to accept the .257 Wea mag. While I was having the bolt face opened up, I would do myself a favor and also have a Sako type extractor put in. It will add about $75 to the job, but will save you some time, trouble, and expense somewhere down the road.
