22mag to 22-250 Rechamber

[PHATINJUN]

Not to bugger-up Wreckhogs Jet post anymore than I already did I started this. Now I know Longtom has a 225win from a Jet and I did a 225 with a 1-9" twist and was not able to do 4000fps as I needed to long and heavy a bullet in that one so I sold it.But for some reason I keep thinking about trying it with a 1-16 twist I got a Jet and a Hornet in 1-16 but can't bring myself to rechamber those plus they are lighter contour bbl's and I think would heat up quickly. What do you guys think would be possible with a 22mag and it's heavy bbl with the 1-16 twist. I am fairly new to reloading and consider myself ballistically challanged . Not sure how much Longtom has tried to push his so if you could post some of what you have tried to do or anything any of you other guys think about something like this.Plus you guys with the Bees and the Zippers Stimpy ,Marv.and as always Tim you crunch the #'s Thanks in advance .Kurt
PS I got a ss22-250 bbl that I got real cheap but the lug is butchered for the most part beyond repair and I think epoxies would just have to be redone to much to keep it shooting it is in the reweld realm.

kurt, i might be outta line here, as others have proved many times....
but ain't the 22mag on a sportster receiver ? and will it function on a sb-2 receiver ?
are the sportster receivers strong like the sb-2's ?  and did they make a 22mag on a sb-2 receiver ?
i do know that the 22-250 has a mighty stout chamber pressure.
or maybe i jus don't understand what your asking !!!
gotta remember that i'm from alabama

Kurt, I think the softer 1137 rimfire barrel will shoot the throat out pretty fast in the 22-250, but many here have used rimfire barrels on SB2 frames such as Stimpy has done with the Jet and Bee, there have been a couple 17 Remingtons done with .17 rimfire barrels also, but I don't recollect anyone shooting them much, I know Larry had some real accuracy problems with his before he sold it.

John, a rimfire barrel will or can lock up fine on an SB2 frame, SS1 Sportster frames are cast iron just like the SB1 shotgun frame, they just put the firing pin in the wrong place on the Sportster frame to work with a centerfire barrel.

I had a 22-250 barrel with a 1 in 17 Twist and it would still shoot 55gr bullets.  Mine was on a Savage 10.  You may be able to find an older .223 barrel, but a nice hornet barrel would be the way to go.  My gun would shoot 40gr bullets a little better than 4,400fps.  Larry

I kind of forgot about the bbl being 1137. And I believe the speed I'm looking for may prove to much for it. Larry I got a couple of 1-12 223's but if I rechamber I don't think I want anything less than 1-14 that's one of the reasons I was looking at my 1-16 Hornet. Now I may think about doing my Hornet bbl to 22-250 and rechamber the 22mag to Hornet or something else. maybe welding the butchered bbl or maybe even treat myself to a new 22-250 with the new Handi Grip. I don't know why it's just the sickness I guess. hell I got three right now that ain't been to the range yet. Kurt

I have been focusing on the .225 Winchester this summer.  So far just researching loads.  I have just acquired a 1:9 .223 bull barrel in 24" length which I intend to have re-chambered to .225.  Now I have not worked up any loads, just theory.  The Winchester powders 748 & 760 are low pressure powders with a low flash temperature.  I choose that caliber to focus on because of the powder savings over the .22/250.  I plan to use 75 grain bullets & 760 powder.  Now the key is according to the data, there is 10,000 PSI more room to go up over listed maximum load.  You may want to reevaluate.  Softer steel 22 barrels are not the answer to save money.  Can't get better value than a Handi barrel.

If you can get the hinge area filled with some weld, I have a 3/8 mill that I used to cut the new hinge for the shortened lug on the last project.  It is really easy to do and ends up with a better hinge cut than H&R makes.  Larry

Larry we'll see what I end up with . You just may find a BBL in your mail one day  . Topper mine was a fluted 24" and if I remember correct I used Sierra 69gr bullets with I think IMR 3031 to make sure the bbl on my 225win would at least shoot and it did shoot pretty good right around 3600fps IIRC but at the time 69gr and 3600 fps was headed the wrong direction .I did feel that I could even get some of the real heavy 224 bullets to fly. I do also believe some of the guys who like the 223 for deer would benifit from the Handi 225 Winchester and heavy bullets. Not sure what your meanin about savin money on the bbl's that would be a first for me. ;DKurt

Amen to that, night and day difference!

I don't know how it will last, but the barrel Larry rechambered for me is lights out, in .17 Fireball.

My 17 FB on a rimfire barrel is trucking along nicely.  It has 200 plus rounds through it and the > 1/2" accuracy is still holding up.    My 20 Horn Vmax load runs about 3800 fs.  RL10X is proving to produce even smaller groups. 

I don't know what the metallurgy parameters are with the specific steel used by NEF/REM...it will have a different flame resistance than the 4140 steel so may or maynot last.  Anytime you get over 40KPSI you will get burned steel and cracking in the throat area but the muzzle end is where the accuracy is made or lost.

It will be interesting to see just what happens.
