Rechambering to 22-250 A.I.

[lone ranger]

After watching varmint DVD's & seeing spectacular shots with this caliber, is that a big job to rechamber a stock Rem. M700 VLS s/s fluted, H-S syn. stock, practically new to the Ackley Improved version?.........or would expenses for this factory barrel be about like a new custom barrel with that chambering...........that is the question & thanks.

To do it right, the barrel should be taken off and set back some amount. For one, to give a fresh throat and also to set up so that you have the proper headspace. When rechambering to an AI cartridge the headspace should be set so as to have about .004" of crush on a standard non-ackley case. And then index the barrel. I charge the same to do this as I do to chamber a new barrel. The benifit of a top quality barrel would certainly be worth it to me. ---Mike Ezell

Nope but it looks like I need to contact my web guy though. It's been a long drawn out process getting that site up and going. Looks like it'll draw a little longer. Shoot me a message if I can help in some way.---Mike Ezell

If the factory chamber is concentric, not oversize, and true to the bore then rechambering is an okay option. Usually removing the barrel, trueing the action and lapping the lugs will give enough set back to have the proper headspace on the improved chamber. I am not a great fan of redoing factory barrels, but when it comes to prairie dogs they can be a cheap source for some fun and then fire forming brass for you new custom barrel at the same time.

Had a great shooting 22-250 wear to the point the barrel need to be set back or replaced at a time when I could not afford to replace it.

Had a good smith recommend I set it back and so I did and had it made into an AI. Shoot 400 F/F loads at PD's that summer and about another 800 the following 2 yrs. It still shooting little bitty groups but it had about 4000 rds, hot rds, thru it when I had it set back. When it goes this time I'm ready have enough to get a new barrel and it will be an A. I. just too much fun.

With a Varmint contour factory barrel, it's nice to just cut off the complete thread shank. Then rechambering and of course rethreading tends to clean up everything nicely. Might want to check the throat for firecracking before running a nice sharp reamer into it. If the barrel shoots well as a factory chamber it should shoot well as an improved,,or possibly a bit better or worse [hopefully and usually better, but there's always a chance].
You did say a practically new rifle so it should refit fine.
A custom barrel would increase the price just the cost of the new barrel,,,unless you want it polished, blued, or other extras such as open sights installed [of course not on a varminter, right?]

If the barrel looks good inside and shoots well, it's worth rechambering. Might as well use it and have fun. Factory barrels can be really accurate, but the downside is that they copper a lot more than custom barrels and it takes much longer to get them clean. If funds aren't a problem, what I'd do is get a custom barrel and have them both done at the same time by someone who's good. Enjoy the rechambered barrel, shoot the crap out of it, and when that one's fried take it off and screw the new one on. If both chambers are done at the same time, headspaced the same, brass will work just fine in the new barrel.
