I have a Super 14 barrel that was rechambered from .223 Rem to .225 Win. T/C says .225 Win develops to much CUP (50,000) for the Contender. Using Hodgdon Powder manual #26 & Hod4831 (start) load 35gr (33,600CUP) shooting 55gr bullet, shouldnt this be safe in the Cont-ender when MAX CUP for cartridge this size I figure would be around 39,000 CUP. Have shot this load with no signs of excess pressure, but welcome opinons of those more experienced with Contenders than I.

well maybe

Yes I am sure with PRUDENT reloading practices is is safe.
Are you going to KEEP the barrel?
Will you sell it?
Will the person you sell it too be as PRUDENT in reloading?
I just cannot get into unsafe chamberings.
You can chamber a 458 win mag in a contender and use squib loads and be safe>>>>>But why?
I know most feel they are safe and more than expert in their firearm saftey.
What happens the ONE time they are not?
I would rather stay with a SAFE chambering
Most of these chamberings that must be DOWN Loaded to be safe were done by Gun Smiths that are NOT too concerned about you saftey
OK just my opinion

Ken55,
Of course if you use it wisely, you will be safe. I would recommend marking it somehow to not use factory ammo or factory reloading data if you ever sell it. If you really wanted to ensure safety you could have it rechambered to 226 JDJ and that would alleviate any issues with the safety of that particular barrel.
I wouldn't go out and rechamber a Contender barrel to an inappropriate chambering, but there's no need to get rid of it as long as your treat it safely as you have. Thomas does have a good point about you selling it though, that's why I mention the above.

regards,
Graycg

I would be leary of ever selling it! In this day of legal finger pointing you could be on the wrong side of the liability suit with this one. Just my fearful opinion, KN

Ken,

I've thought about a similar rechambering, but decided that a 6mm bore diameter was a better choice for a 14" barrel and a case capacity of this size. I'd be glad to hear how the barrel performs.

The 225 Winchester has the same style of thick head 30-30 sized brass used in the 375 Winchester, but with a smaller rim. The 375 winchester is a factory chambering for the Contender and operates at 52,000 CUP, so you shouldn't have any problems with your 225 unless you get wild with your reloading.

The .375 Win is a straight sided case, while the .225 Win is tapered. This will likely lead to more back thrust with the .225 and is why the JDJ cartridges based on the .225 case are blown out to be more straight sided. The .226 JDJ suggested above also has more case volume than the .225, as well as the straighter sided case, and thus develops less pressure and backthrust for the same powder load. I agree with the previous posters that you should be concerned about what happens to the next person to get hold of this barrel. If it were mine, I'd send it to SSK and have it rechambered to .226 JDJ.

Ron,

The 375 Winchester case is tapered the full length. I wish it were straight as then I could get carbide dies for it.

The 225 Winchester tapers from .423 forward of the rim to .407 at the shoulder over a distance of ~1.5" of casing length The 375 Winchester is .423" forward of the rim and tapers to .400" at the case mouth over ~2" of casing length. So for practical purposes, there isn't any real difference between the taper of a 375 Winchester case and that of a .225 winchester case.

I ended up with this barrel in a trade, before I knew about the pressure problems. Why someone rechambered it from 223 to 225 is crazy (dumb) the guy even signed his name on the barrel. As I'm stuck with it & I've already bought dies for it I plan on keeping it. I just have to stay with what is the starting load & be happy with it. Would be interested in looking into the .226JDJ. What cartridge is it based on ? As far as shooting the 225 I just have to shoot handloads in it & I have no complaints with how it shoots.

Ken55,
the 226 JDJ is based on the 225 winchester case blown out and improved, the whole idea of it really is to give more case space so that you can load more slower burning powders to get higher velocity at lower pressures. It will also have enough extra case volume to reduce the pressures to a safe level in the event that someone fired factory 225 winchester ammo in the gun. I don't think it costs more than about 65 or 75 dollars to rechamber it. Not sure what the dies cost these days, but they are more than regular factory dies.

Right now I am waiting for the brown truck to bring me a 14" Contender barrel that Dave Van Horn rechambered to 226JDJ. I don't recall if we even discussed the price when I sent it to him, but it was in the neighborhood of $75. This barrel had already been rechambered from a 22 Hornet to the 225 Win. The smith that did the job let the reamer chatter and pretty much screwed up the chamber. When I sent it to Dave we discussed the options and decided the 226JDJ was just about the only one that was practical.

As to the dies, if you have SSK do the job, they will sell you dies. I'm told that they are somewhere around $85, but I didn't call them. I am having several sets made by CH4D. I'll be happy to share them if anyone has an interest. Redding wanted $125 each and a $42 set up charge. Since I'm getting 6 sets made by CH, the price is substantially less.

Also, if anyone has load data available for the 226JDJ, I'd appreciate seeing it.

I have a question..If , as this thread suggests, the .225 win at 50,000 cup is too much pressure for the contender, why is the .223 rem at 52,000 cup safe in the contender?

Shortgun,
Everything about pressures in the Contender revolves around the diameter of the case, 223 is skinny and can take factory pressures just fine, 225 is wider across the diameter and should be limited...limited to what is an whole 'nother can of worms, but probably around 45,000 psi...Just to be safe.

Hope that helps.

regards,
Graycg
