I got the barrel back from the smith and have just finished re-building the extractor plate to work with this new cartridge in place of the .17HMR that was the original caliber.I can't wait to shoot this round--it specs at 4200 fps muzzle velocity.This combo may be my new turkey gun ,but it's definitely gonna be a heck of a varmint shooter.
After talking and watching the smith re -chamber this barrel,I think I'll try to do the next one myself--I have an extra 24V-A barrel in .222/20 that I can't use so I may as well go ahead and re-chamber it for 22-250.We'll see what happens!

Forgive my ignorance but why would you want to rechamber a .222 to 22-250? This isn't a bench rest level rifle to begin with. I have a .223/20 and it is not a tack driver by any means.

Sounds like a bomb waiting to happen.

Well sometimes I like to try things that maybe I shouldn't try ,just to see if I can do it--anyway that 222 barrel set doesn't shoot from my 24V-D recievers so it wouldn't be a great loss if it does blow up

How 'bout your eyes or fingers? I think they'd fall on the Great Loss side of the ledger.

Easy guys....Kelly might be a redneck, but he's not a stupid one.  SAAMI says maximum pressure on the .222 Rem is 50K CUP, while 22-250 is 50,400. He's not a handloader, so he'll be buying factory ammo, which is always (well, almost always) loaded below maximum pressures (although the price of 22-250 ammo may encourage the handloading thing). Further, his .222 Rem has a 1-14" twist, which is also a common twist for the 22-250. The question would be if his barrel has enough diameter to allow for the extra .212" (1.912" vs 1.700") longer length of the 22-250. That's not really very much difference. Since Kelly's already addressed this issue with a much larger difference in the two .17 cartridge conversion, he's probably good to go.* If it does and if the barrel is a throw-away anyway, why not learn a new skill? Heck, if this works, maybe we'll all be sending him barrels to re-chamber! *Actually, the .17 HMR conversion to a .17 Remington is a much bigger jump: .17 HMR pressure is about 25,600 psi vs. .17 Remington's 50,000 CUP. 17 Remington is over an inch (1.092") longer than the 17 HMR (2.150" vs. 1.058"), so his gunsmith took out a lot of metal. But since there are lots of Mdl 24s chambered in calibers 50,000 CUPS/psi+, he's (again, probably) OK. |

You betcha, Kelly.....let us know how the re-chambering went! I presume you're renting the reamer?
