225 Win rebarrel question

[Rayboy]

I have a Savage mod 340E in 225 Win and it needs a rebarrel. I am wondering if I can buy a 223 barrel for a mod 340 and have it rechambered to 225. Any thoughts? Thanks

 

[Preacher]

Don't see a problem doing that...

The 225 win is a rimmed case. The bolt face and extractor will probably not grip a 223 rem case.

 

[Kylongrifle32]

Sorry did read you post close enough. Rechambering from 223 rem to 225 win should be doable.

I think I have a reamer if you need one.

Why go out of your way to get a .225. Worst shooting caliber I have owned.If paying for a recharger get a modern caliber no matter what caliber your choose.

Not altogether sure the problem is the cartridge per se. I have a second (or third?) hand slightly modified post-64 M70 in .225, and it's an absolute tack-driver.

I call it my ugly-duckling. It's all original, with a couple of modifications. The original shiny stock with pressed checkering has a misfitted recoil pad, and someone glued the barreled action to the stock. Before that happened, someone did a little trigger work on it, and that's the only positive modification it has.

So original barrel and action. It came with an old cheap-but-adequate Tasco scope, dies, brass and about 200 rounds of reloads (I know the reloader) for $400.

The rifle shot so well I gave it Nightforce NXS 5-22x50 scope.

It has a 1:14 twist, so I must keep bullets below 55 grains (longer bullets don't stabilize, some tumble).

But with this rig, I've shot numerous 5 shot groups < 0.5 MOA.

I suspect any inaccuracies are with your rifle(s) or, perhaps, trying to shoot too long a bullet in a 1:14 twist barrel.

The guy I bought it from provided a target with a 0.267 MOA group (5 shots). I myself have shot (5 shot, MOA) groups of: 0.420; 0.192; 0.407; 0.377; 0.268; 0.407; 0.287; 0.412 & etc.

I’d go with the 22-250, it’s all the 225 was and some. Plus good availability of good quality brass to boot. Easy Peasy

Don't see what the problem would be. .225 brass is scarce, but you obviously have .225 brass or you wouldn't be in favor of keeping the same caliber. Also could be that your magazine was designed to feed the rimmed .225 case (the Win. M70 used a special slanted mag. box for the .225), and may not feed a .22-250 well. Nothing wrong with the .225 -- had a couple of the M70 varmints years ago and they were sub 1/2' MOA with handloads, so I don't think you would be handicapped by the caliber.

Novice here with a question to the question. If you buy a .223 barrel and rechamber it for 225, will the twist be what you need? I am assuming the rifling would have already been cut in the .223 barrel you mention purchasing.

Here's my very crude take on this.

The issue is twist rate (1:14? 1:12? 1:11? 1:9?) vs bullet length. Many discussions center on the weight of a specific bullet and use the weight as a proxy for bullet length. But, for a given velocity, the key parameter is really bullet length. Link

As a rule of thumb, for a given caliber a faster twist (1:9 vs 1:14 for example) will stabilize a longer bullet. A slower twist rate (1:14) in my .225 will not stabilize most long bullets, and some have key-holed on me when I've tried them out.

So, if you use a relatively fast twist barrel you trade high initial velocity for long-range accuracy, because the longer bullet (which typically weighs more than a shorter one) is more wind-resistant and aerodynamic than a shorter bullet.

The shorter bullet will shed its velocity more rapidly than the longer, heavier one and at some point the longer bullet's velocity will surpass that of the shorter bullet.

Just my understanding of this.

Why shoot the same thing as everyone else. I say stick with the 225 Win for the something different/oddball factor, especially if you’re happy with it.

I believe he is asking if he can re-chamber a 340-223 barrel to 225 Win. I see no reason why not, it might be easier to find a 222 Rem barrel.

You are probably right and the .222 twist would probably be the same as the old barrel, if Savage used the same twist (14) as the Winchester M70 .225.

Many years ago a friend had a post 64 M70 Varmint in 225. I had a M700 Varmint Special in 22-250. We crow hunted a lot. Our bullet of choice back then was a Hornady 53gr Match. On paper or feathers, his 225, as homely as it was, would shoot with the best.

Win 225 is just a rimmed 22-250

Now you've done it! You have opened the door. You're going to hear from all the .22-250 owners who believe their rifles to be superior to all other .22 centerfires.

 

[Tommie]

Not quite. But the .225 does has comparable (albeit somewhat slower) velocity. Really the .225 winchester is more similar to the old .219 Zipper Improved. It’s a shame the cartridge didn’t catch on.

 

[Shawnba67]

I would think a faster rate of twist would be nothing but benefit.
