260AI or 308 Win

Re: 260AI or 308 Win

I've got two AI chambers. One is a .280 AI and the other a 6mm AI.

Both have been proven to be superior to the Remington offerings. Both rifles are superbly accurate so far and easy to load for. However, I'm not sure this would be the case on the .260 Rem.

If you answered "YES!" to all these questions select the .260 Ackley Improved!

Otherwise, build yourself either a standard .260 Remington or a .308 Winchester and spend your free time on the range shooting instead of being stuck behind a reloading bench trying to figure out the "What NOW?" reason why your groups went to shit.

And I haven't even touched upon all the fun you can have getting a .260 Ackley Improved to feed reliablely from all your mags ...

I would have to disagree a little! A buddy of mine has a 260AI as well as some other guys I shoot with, never heard or seen anyone of them complain or had problems with it as far as finicky or groups going to shit. The one guy I shoot with all the time has his set up with a standard acics mag and it feeds with ease. As far as loading I think we tried 2 different loads and they both worked great only differnce was 2 different powders, so he loaded everything up and hasn't had to toy with it at all. I really would like to know what issues you've had in a little more details because honestly I've never heard anyone say anything close to your post about the 260AI other than the case prep being a pain...</div></div>

Hillbilly,

Typically, I find that when I run across AI reloaders in one caliber or another the ususal suspect is that they try to get speeds of the next cartridge up in volume. IMO, one of the benefits of all AI cases is that they last longer with less fuss. However, the killer with them is when guys hot load them, and most do at some given time of owning them, the case stretches. When it stretches it's harder to get it to form back down like a more tapered body and shoulder.

I've not noticed groups going to hell so bad as I've seen guys beating their bolts closed. I think it speaks for itself how someones group is going to turn out though, when he's pissed and his hand hurts from beating his bolt closed. </div></div>

I agree with you on AI reloaders run there rounds hot at one point or another! But as far as building a 260AI and running it hot and screwing up the brass I wouldn't want to push it that hot not only to lessen the brass life but also the barrel life. If you wanted to push a 260AI that hard build a 6.5x284 but your right back to the 800-1000 round barrel life. I also agree if your all pissed off fighting the gun why even try groups there gonna be shit no matter what. Other than case prep I see no other real problems with the 260AI and fireforming isn't even that bad. Tho I was leaning towards a 6.5 Creedmoor and found out id have to buy the reamer for my gunsmith to use I redirected toward the 260AI. Thanks for everyones input I've picked up some extra knowledge towards the 260.
 
Re: 260AI or 308 Win

I guess my next question would have to be what barrel length? I know the round was developed around the 26 inch barrel but has anyone run it shorter and still got good results?? I'm thinking 24 inch barrel and I can't see 2 inches affecting it that much but id rather see what everyone thinks before I get a barrel chopped!
 
Re: 260AI or 308 Win

If you're worried about the barrel length, why not start long and see what you get? If its where you want to be, then so be it. If not, you can always cut it shorter, but never longer.

That all well and good but I know it'll work out of a 26 inch barrel. That's why I'm asking if anyone has built one using a shorter barrel

I've seen a lot of .260's running pretty good with a 24" barrel. I don't think there is enough case volume to make a difference between the .260 and AI as far as one working and the other not. Velocity left on the table would be about the same with either. But not excessive.
 
Re: 260AI or 308 Win

I have a 260 ackley and i really like it. It gets 6.5x284 velocitys with 5-7 grains LESS powder. Less powder=longer barrel life.
The fire forming was easy using the C.O.W. method as to not waste the bullets.
I have a fast load that i use for hunting and a slower load i use for steel. It's good to know that if needed you can run them hotter. If you get the standard 260 your stuck with what it gives you.
It feeds fine through the stock remington mag ,old stock, as well as the AI mags, new XLR stock.

just my 4 cents
