280 case shot in 270

[jimmb]

At the range today doing some range patrol (not a drill sargent) Was talking with some of the shooters. One guy shooting a 270 was leaving his brass on ground. I picked up and saw it actually was headstamped 280. So evidently he sized a bunch of 280 down to 270. I saw his groups and they were pretty nice. Question for you guys is.... Could a problem have arisen here? He did not have any tight extractions or anything odd and again his 100 yard group was good for deer.... thank you, JIm

If he F/L sized the brass in a .270 die he was safe.

Brass formed that way will be a few thousandths of an inch short, but otherwise should work fine. I'm surprised the shooter could find .280 brass easier than .270. Not the most popular round.

Who takes the time to form 270 brass out of 280 and then leaves it on the ground?

The only thing I could see that could happen is when you neck down, the neck walls get ,001 thicker. That means a loaded round would be .002 bigger. In some guns it could be a bit tight. Matt

Years ago I bought a box of Federal hunting rounds in 270. When I went to use the ammo, there was a 280 round in the mix. At the store the ammo was on a self where anyone could pick it up. I wondered if someone might have switched a round on purpose. Happy I found it before I tried to shoot it.

It wouldn't have chambered, with it's longer shoulder. But might have jammed in the throat when you tried to chamber it. Could have ruined a day's hunt until you had access to a cleaning rod.

The guy who loads it so hot he knows it wont hold a primer anymore
