With the new powder, the 270 AI seems faster than a regular 270WSM and almost a Weatherby- It looks like with biger bullets that it might surpass the 280 and 280AI in capabilities too?


And if you load 17 into the WSM and WBY you will get higher speeds.

Pressure for pressure with the same barrel length, no Ackley
round is going to get within 200 fps of a magnum round.

Outside of saving yourself time trimming brass the Ackley is
most overrated. You can load it's unimproved daddy to within
50 to 75 fps of it.

A 26" 257Wby doesn't have 200fps on a 24" 25-06AI....let alone one in 26" That ain't a guess.

A 24" 7mmRemmie doesn't have 200fps on a 280AI...that ain't a guess.

'Course,I shoot em all................

I liked the bumper sticker I saw in Montana that said
"You ain't S*** unless you have a 280" only thing wrong it should have been a 280 AI.

270 is hallowed and sacred don't mess with it. Besides a 270wsm will beat the 270 AI with no great pains. If you really want to trump them all get the 270 Roy and be done with it.

My Tikka T3 with 24" barrel chambered in .270 WSM is no faster weight for weight than my 24" .270 Win.
Not only that but the WSM's (I've owned the 7 WSM and the .270 WSM) were a pain to load.
I haven't even mentioned the fact that the WSM's have the less than optimal rebated rim on them too.
.270 Roy I'll give you. Very nice round.
To the original poster I'll say again that the plain old .270 Win WITH A 24" BARREL will give you more of everything than a 22" .270AI.
You have to pull the barrel to do an AI as well so I'd recommend either buying a 24" barrel for your present rifle or find a 24" rifle already chambered to .270 Win. They are plentiful for you right handers, not so much for us lefties.

I'd be interested for a quoted reference from Jack O' re: the 24-inch .270, for, IIRC, he shot and recommended the 22-inch version, claiming 3140 fps in his handloads using 4831.

Why don't we just say that the difference between a 270. 280 Ackley and a 7RM is basically the same, up or down. I'm a reloader so you might as well add the costs to reload each if discussing all the merits. 280 brass is cheaper than 7 mag and in a pinch you could use 06 brass as well for the standard or Ackley version of the 280. Less powder, recoil, muzzle blast and usually packaged in a light config make the 280 Ackley more attractive to me than the 7RM. Unless your ammo doesn't make it to your destination for some reason (and everything it was packaged with) ammo availability is a non-starter for me. For me, it's the sum of little gains that make the whole package more attractive than either the 270 or the 7RM. Won't argue the paper ballistics cause that's all that it is, paper and arguing.

On page 1030 of Ken Waters' pet loads 8th edition Ken writes;
"In a letter years ago, Jack O'Connor told of two of his .270 Winchester rifles, one having a 22 inch barrel that chronographed 95 fps less than his 24 inch barreled rifle with 130 grain bullets and the exact same load. It's interesting to note how closely that difference agrees with my findings."

As for Mr. O'Connors preference I have no information.

A few yeas ago somebody, I think it might have been Boddington, did a comparison of the .270 Win. and .270 WSM. He used the same rifles with the same length barrels. He said that with some loads the WSM was faster and with others the .270 Win was faster. At the end of the article he said if he owned one or the other he wouldn't sell it to get the other, not enough difference.
