Hi guys,
Got to ask, would you re chamber a Remington 700 .270win sps into a 280 Rem or rebarrel a Abolt 300WSM, into a 7mmWSM?

cheers

In order for a .270 to become a .280, you must rebarrel not simply rechamber; .277" vs .284" but you know that. What do you hope to accomplish with the switch? The .270 and .280 are so close in performance that there is no practical difference that could be distinguished in the field, and maybe not on the range either. Ditto with a switching a .300 WSM to a 7mm. Performance overlaps in both cases, and all of these cartridges are excellent choices for chambering in a general purpose big game rifle.
 
If you just want to try a different caliber it'll be cheaper to just buy it. It is different if you want a custom barrel anyway, and are just swapping calibers while you're at it. Practicality is not a requirement in this hobby.

A side note; rebarrelling an A-Bolt can be problematic. Some gunsmiths won't even touch them because the threads are known to sometimes gall and pile-up when removing the old barrel.
 
Don't change the 300 to a 7 because simple math will tell you that 300 is way more than seven, so it must be better. As for the .270 to .280, go for it. .280 is ten more than .270, so it's ten better. 20 better than a .260, and 30 better than a .250. Actually, the .280 is only 20 less than .300 so you might as well take it all the way. What's a measly 20 more...
 
So...you want to take one of two similar rifles, in two functionally-identical chamberings, and change one of them into one of two other functionally-identical chamberings, which also happen to be functionally identical to the first two?

This sounds like an incredibly elegant and efficient method of wasting time and money.
 
So it is not too far removed from other responses but what part of "NO" don't you understand?

The difference between a .270 and a .280 is 0.007".
I sold my .270 after I bought a .280 Remington, and my son always had his dibs on the .30-06.

One of my bigger mistakes was having two rifles in 6mm Remington and since then have vowed to never have two rifles in the same calibre (i.e. .280 and 7mm).
With a barrel and gunsmithing costs, you could easily buy another rifle without a scope.

If you ask yourself or even tell us what you intend to accomplish that may be a matter of solving your question.

Perhaps my signature might answer how I feel about your question . . .

That about sums it up.

One other suggestion you may consider if you want a slightly more hairy chested 270. A simple re-chambering to a wildcat known as the 270 Gibbs. You will have to fire form your cases and reload your own ammo but it would be cheaper than a re-barrel as Boomer has described.
I am sure you can google lots of information on the family of Gibbs chamberings, all based on the 30-06 case. They range from 240 to 338. I happen to have an old Husqvarna FN Mauser that I re-barrelled to 340Gibbs. Great moose gun. It is not quite a 338 Win Mag but with bullets up to 225 grains, it ain't far off. It has a bit of an edge over the 338-06.

I agree.....if your going to spend the money to rechamber a rifle, make it somthing sweet. Otherwise just go buy one and sell your current.
