I am looking at a used, but LNIB Model 70, Classic in 7MM STW. Is has a syn. stock and a 26" ss barrel. I don't have any Winchester bolt action rifles, so how well can I expect this to shoot? Any opinions on this rig?

It may shoot great, it may shoot lousy. You'll never know until you start pulling the trigger.
My biggest concern is with the caliber.
It's just a "tad" (and I'm being sarcastic!) bit overbore, and has a reputation of eating the living hell out of barrel throats and leades. Downloading helps extend barrel life considerably.
What's the asking on it?

I've owned several M70's in everything from .243 to 300 Mag. All shot fine, although a couple needed some fine tuning to get to "minute-of-gnat's-????" groups.
My brother has a Remington 700 in 7mm STW. It's a heck of a cartridge in terms of flat trajectory and sheer knockdown power. The downside is that new ammo is horrendously expensive and the muzzle blast is downright brutal. Needless to say he only shoots it when he thinks the situation calls for that much punch. I wouldn't doubt that barrel life would be significanly reduced, but no more so than some of the other "ultra-magnum" class cartridges.
If you roll your own, you can load the STW for about half the price of new ammo. 7mm bullets come in a plethora (yes, plethora!) of weights and configurations. The only downside is that the large cases eat powder at much the same rate a top fueler gulps nitro. Still, it's cheaper than the $30-$35 per box my brother currently pays for ammo.

Gentlemen: Thanks for the info. The price quoted to me was
$525.00 . As I said, it is LNIB; doesn't appear to have been fired.
I have a custom , Mauser 98 action in 7 x 61 Sharpe and Hart.
I was "musing" about the cartridge(7MM STW) and the shop owner told me he had one and could give me a deal on it. Will have to bear down and decide. Thanks, again .

You might want to go to a local Walmart before buying that M70. Mine has a M70 in 30-06 with 3-9x40 scope new in box for 400$.

What else is IN the "7mm ultra magnum class"?
As far as I can tell the 7mm STW swallows upwards 20 grains more powder than its nearest competitor, and in that case that's got to be very close to a compressed load...

Thanks for the tip, but I much prefer to support my local gun shop. I am not in the market for a 30-06, but that is good to know.

Why not get the Sharpe and Hart reamed to 7mm weatherby? Only 150fps less than 7mmstw and a 98 action is prolly better than a new Win(maybe) + you are familar with your mauser AND it should cost no more than $120 + shipping for a first class job!

Uh..Gordon...did you miss this ?

Oh, the 7mm Remington Ultra Mag, the 7mm Winchester Short Magnum (and new WSSM), the 7mm Weatherby Magnum...
So? Just because the case "swallows upwards 20 grains more powder" is no indicator of performance. In this case it just goes to prove that the 7mm STW is relatively inefficient when it comes to propellant volume vs velocity. The 7mm WSM and new 7mm WSSM are ballistically similar to the STW, and use far less propellant. My answer was to show that the throat and barrel wear on the WSM should be no different that other cartridges with similar velocities, hence the 'ultra magnum class' generalization.
retiredsgt wanted to know the pro's and con's of both the Win M70 and the 7mm STW cartridge. I laid it out, plain and simple. If you want to get bent out of shape because of the generalization I used, well, it's your time and you can waste it as you see fit.

You're right, Brad, it's no indication of performance, that's why I never made that association.
That is, though, why I used the word overbore to describe the 7STW.
7mm with upwards 100 grains of powder behind it? That's not just overbore, that's overboard!
The 7mm Weatherby doesn't have a nice reputation on throads if you don't use Roy's "freeboring" system (I think that's what he called it).
I can't even begin to imagine what this cartridge would do to a barrel, or how many shots it would take to do it.
Sorry, when it comes to being overbore and overboard, the 7STW simply takes the cake.
"this case it just goes to prove that the 7mm STW is relatively inefficient when it comes to propellant volume vs velocity."
And that, my friend, is one of the truest indicators of whether or not a cartridge is overbore or not.

Gentlemen: Very Interesting, indeed! I talked to a Tech. at Sierra, and he stated he thought the round would be very rough on a barrel. But, I am a "tinkerer (sic?) " at heart. Love to get a gun and try to get it to do its best. I have several rifles, but have never had a Winchester Model 70.
Yhanks for your help.

I have a Winchester Model 70 Classic Laredo in 7MM STW with a 26" heavy barrel and I like it very much.....as far as shooting the barrel out, I don't think the average shooter would ever do it.......get the rifle, you will like it, but, get a reloader since it is like any other magnum, ammo is expensive..........Remington makes fairly decent priced ammo for it....
