I've got a Remington 220 swift that the barrel is about shot out on and am wanting to rebarrel to something different. Im thinkin going 220 swift ackley, 260 ackley, 243 ackley or build another 25-284 since I sent my last one down the road. The gun will basically be used for anything under elk unless I decide on the 260 ackley or the 25-284. What would you guys do and how would you build it?
Sounds like your no stranger to AI.
So I would say.
6.5x47 if you don't feel like fire forming.
And if you do want to fire form.
I'd take a look at this.
http://www.6mmar.com/65_SuperLR.php I'd skip 220 Swifts, 220 Rockets as I dont like the shoulder angle of either one.Same same for the 260 and the 243 WCF.
If you shoot alot 30 degree shoulders and long necks are your friend.

I would go .224 or .243 and skip the .25 and .264 offerings.
Just me, but I would go to 7mm instead of the 6.5 and the 6mm offerings are hard to beat.
6-284 or 243 AI in a 6mm bore or 22-250 if you chose the smaller bore.
If your Remington 220Swift has a factory barrel it is a 1-14" twist, A 220Swift with a 1-8" barrel is a whole new animal or try a 22-250AI also twisted 8.
If you want to go to 6mm my fav has been the 6mmAI also 1-8"
6.5's are what I'd look at.
Fireforming is for the birds. My 22-250AI will be a 260 someday.

Good for you
fireforming doesnt bother me a bit
.220 AI and an 8" twist.

If I ever do another fast 22 it will be something simple like a 22-243. No wasting powder, bullets and barrel fireforming, and no feeding issues.
I feel like an 8 twist 243 Ackley would be a total blast... Heck I'm excited for mine with a 1-9er.
A would not be excited about a 243 with a nine twist.
Good thing it doesn't have to excite you, I suppose.
It'll stabilize 105 A-Maxes, which is the only bullet I've got major plans to shoot... 115 D-Tacs would be a hoot to use, but those will have to wait till something with a 7.5t comes along.
I have a swift since 05 and thought if barrel goes I'ed stay swift but tighter twist. I also have a 6.5 Cmoor 1-8 Hart barrel and trust me the swift has become a safe queen lately,just sayin.....
It'll stabilize 105 A-Maxes,
Doubtful. Mine is a 9 and won't stabilize the Amax or the Scenar. They start drifting past 100yds. Why drop money on a chamber job for something that is not proven? Get a 7.5 or 8 twist and do it right.
I have a Rock Creek 10 twist that will stabilize 105 amaxs out to 1000 yards.
Brad Arnett shoots 1-9" 243 AIs and hangs sub MOA to a grand.
Not arguing with your experience Drew, I'm just confident my 9 will work fine for my intended purposes.

That's a good idea... Hmmm...
Wonder what speeds a 75gr A-Max would get?
Travis
deflave, I have read that 3600+fps is doable.

Just reading that gave me a boner.

Had a 22-6mm. 3500 fps with 75 Amax in 24" barrel. Hornady has data for it in their book.
223 WSSM is really similar in case capacity to a 22-6mm, and higher in capacity than a 22-243. So looking that up will give ya some idea where to stop on a 22-243.

Thanks friend. GFY.

One pull of the lever and your brass is ready to rock too.
Go with a 22-6 if looking for the most from a 22 caliber. It will fit in a short action with a 75 Amax(Wyatt's length box), and won't have the weird throat burning issues the 243 is famous for (and worse necked to 22), due to the longer neck. Dies are readily available from Hornady for around $70.00.
That being said, build a 243 Ackley.
GFY.

Now my head hurts. 7-08 it is.

That's what I'm talkin' about...
^ I'd take a 7.5 twist 6mm Rem and skip the fireforming.
6mm Remington and then go back to hunting
That works too!
.220 AI and an 8" twist.
This suits me. I did my last Swift barrel in the AI, eliminated a lot of trimming. I also think there is a slight difference that the bolt is opened up for a Swift, so the .308 series might not be quite right. Anyone else remember this?
Travis
I WOULD STAY WITH THE 220.
MY RUGER 26 INCH BARREL GETS 4466 FPS WITH THE 40 GRAINERS
AND IT IS POSSIBLE TO GET 4750 FPS.

I Doubt it.

LOL
try the 63g Sierra with 4350 and a win primer. I restored accuracy with this bullet in several barrels due to the fact that it has a lot of bearing surface, and it kills like a sack of hammers!

4466 is doable, 4750 is going to put you square in the mid 70K pressure range which is doable but hell on brass and I would not do it in a ruger.
A 22/6.5x47 is a fun little round, runs right with the swift and you can not destroy that brass.

Eddie, this almost identical to the 22/250 AI, 6/250AI almost identical to the 6x47 Lapua.

Huh? Seriously?
If I disliked shooting this much I'd buy some plaid pants and take up golf.
I love fire forming. A great excuse to get out and blast water-filled recyclables w/ a new rifle!
To the OP's question I'd give a hard look at a fast-twist Swift or 22-250 AI.
