Well, if you fired cases are .008 out of round, nothing you do that rifle is going to help you. Thats unacceptable. Call US repeating. Send it back. Or get one of the local gunsmiths to make a chamber mold. I never sent a gun back to them, but I know remington would even fix that.
It happens. I went through much the same thing with a custom 243. Wouldnt respond well no matter what I tried. After a couple years of erratic behavior from it I finally turned it into trade bait for a 30-06.
The 06 didnt look nearly as good until you started looking at its groups.

Quote: I bought a used 270 WSM stainless classic. Factory ammo produced groups in the 1 3/4"-2" range(100 yds.). I figured it was a short bullet seating problem. My dies arrived and I worked up loads with new Winchester brass and Hornady 140 gr. SST. Same results.
I bedded the rifle, free floated the barrel and glassed an aluminum channel in the forend to stiffen things up a bit. Same results.
Bought a Brown Kevlar stock. Pillar bedded and free floated the barrel. Same results.
By now I am out of new brass and reloading the once fired stuff. It's sort of difficult to chamber and the measured brass is .008" out of round.
I guess the only thing left is a rebarrel. Even if it shot well I wouldn't be happy with that chamber.
Damn it!
As I read your Q, you only worked up the one projectile, the Hornady 140 gr. SST. Seems to me that some bullets and actions just do not mix, and a guy should try further afield in bullets before putting all the blame on the rifle?

I have actually tried Remington 130gr. core-lokt, Nosler 130gr. partition and the Hornady 140gr. SST. The Hornady was the last I tried and in the interest of condensing the thread I left out the other bullets and several loadings with each bullet. I have tried three different powders and 2 different primers.
I agree with your idea that some bullets and barrels just aren't compatible.

A lot of times .270 rifles won't shoot 130g bullets very well, but really shine with 150's, such as the Hornady spire points. My .270 WSM shot "lights out" with this bullet.

I had a 300 wsm A bolt that was a real difficult rifle to shoot well. I have other 300 wsm that are tack drivers. I think you get a lemon sometines...when you.. do trade it off or spend to have it tuned. Remember if you don't have confidence in what you shoot...you don't shoot well.

I have a 270 wsm kimber that I love...a real tack driver

My Dad's M70 270WSM sucks with 130 grainers. However, it really shines with 90 grain Sierra HPs over Varget and either 140 grain TSXs or 150 grain Hornady SPs over H1000. I have no idea why it won't shoot the mid-range bullets, but quit worrying about it when it churned out solid 1.25" or so groups with 140 grain TSXs. Dad uses that bullet for eveything but varmints, when he switches to the Sierras. A bullet on either end of the spectrum gets the job done.

The WSMs are supposed to bring with them inherent accuracy and efficiency advantages over standard belted magnums. Maybe that's so, at least in theory, but if there's something mechanically wrong with the rifle, all of the paper-and-pencil advantages of a WSM cartridge will never be realized.
