I hear quite a lot about the 280, why not the 270 AI? What are the pluses and minuses of this caliber?

One plus is it fits in a short action, thinking it's called a 27 WSM...grin

One minus is it's no longer a 270 Winchester

OK you guys... somebody just had a thread about a7mm cult, and you, plus a buttload of others I know worship at the altar of the .277 calibre boolit.
I have never given into the demon .277 diameter, but stick steadfastly with the consummate,ultimate boolit- the .284 diameter....what have I been missing all these years??? \:\(
Seriously, help me out... bring me in to the light....

I have no idea why so many guys do a 280 AI some are the same guys who say a 270 AI is not worth it, maybe the 280 AI deal is fashionable, look at the AR 15 tactical crowd, its monkey see monkey do with them, this may be the same way

if you really wanna go faster on a 270 win case, do up a 270 gibbs

I think it has a lot to do with availability of components (dies and reamers mostly) and smiths who have them.

Its pretty darn hard to find .270AI gear plus a smith who has a reamer in the drawer. 280AI easy as pie.

If you really wanted to get into it the .280 has the slightest advantage. About 2 grains more powder, higher BC's , higher SD's and more bullet choices. That said its not enough to matter in a hunting situation but it is stuff that keeps you up at night. Or starts 50 page discussions in a campfire forum

INGWE: To answer your question it goes like this,and is just my opinion,but if we look back,we see some things are perceived as needing "improving", so they get improved......and some are not.....so they don't.

For some reason, the 7mm's have been played with every which way,and the 270 Win,while remaining enormously popular,has been given scant attention when it comes to improvements.The only exceptions being the 270 Weatherby,and the 270 WSM,both of which make their presence known in the markets,but have only a fraction of the popularity of the 270 Win......so,

I can only conclude from this, that the 270 Win has done just fine all these years,has needed no embellishment,improving, etc,and I think Winchester got it "right" the first time.Just not much to improve upon

From what Ive seen in the field and in the gun Biz ( yeah Ive sold a couple firearms...dont tell the administration!)I'd say you hit the nail on the head..The .270 Win. works well IMO with boring regularity....Ive only seen the .270 WSM put to use once, but it was "flat" impressive.And yeah the 7mm has been messed with in every concievable way,since the 7x57 was introduced as the first smokeless cartridge...only makes sense.By the time JOC and the .270 came along, they already knew how to build a really good cartridge. Bit of trivia, the Germans even had their V1 and V2 ( I think) Rockets built around the enlarged dimensions of a 7mm bullet,because of its perceived ballistic efficiency,IIRC.
Anyway, I'm gonna sneak around to the gun shop and fondle that .270 thingy Dober was talking about! \:D

Ingwe,don't get me wrong because I'm a 7mm maven myself.Provided case capacity and bullets are roughly similar, I see the two calibers as being twins and what one will do the other will do as well.Both are good,both do the same work,and I am finding myself coming down with a hankering lately for a 7x57 \:o

And I can't listen to logical arguments about the 308 and 7/08 being as good as the 7x57,which may be true,but I really don't care...they are not the 7x57 ;\)
