Has anyone heard of or shot one of these? Midway sells brass for it. I've only heard of the 270-338 which pac-nor carries a reamer for. If some one wanted to be stubborn and build something in 270, I suspect this could be a good cartridge if tailored to the 170 berger hybrids. I heard some one has good accuracy success with a 270-308win that I read about on an old forum. Besides decreased BC from stepping to .277 bullet down from .284, the only other downside would be that I suspect you'd need a faster twist out of the 270 then the 7mm which would burn barrels a bit faster. Asking out of curiosity, not so much an interest to build one.
