Over the holdiays, for some reason, three relatives and friends were cleaning out gun cabinets and gave me hundreds of .30-06 hunting rounds. A few of the shells did not look right to me, the bullet was too small, but the stamp read .30-06. I guess a handloader had "necked down" some '06 shells to .270? Just out of curiosity, I tried to chamber it in my '06, and it fit fine. What would have happenned if I had not noticed and shot it?

Big surprise?
Nothing except an inaccurate shot. Since the 270 is smaller in diameter than the 30-06 the loose fit of the bullet in the barrel would not allow excessive pressure to develop and in fact lower pressure developing would not fire the bullet nearly as fast. The bullet would not engage the rifling and would tumble.

I was given some 30-06 handloads, reloader unknown. Never again will I use them from unknown sources. Way too hot. Case jammed in my rifle. I hope the rifle was not damaged. If it was, the damage is not yet obvious.

I was always warned when I started handloading. NEVER use someone else's handloads you just don't know what they are.
I destroyed a gun using remanufactured ammo once so I reload my own for use in the same gun again or buy new now.

...uh, don't do much with guns anymore (I hate cold weather and prefer to fish off of my boat in warm weather). However, 30 years ago I worked in a gun store and owned a .270 rifle. Mixing calibers in any gun, especially high-powered rifles, would be in my humble opinion both very stupid and very dangerous. A bullet has to fit snug to the bore of the barrel as it spins during the travel out of the gun. It is the seal of this fit that forms the barrier for the compression of the powder fire. If memory serves I used to shoot 110 and 130 grain loads from my .270 and fire would shoot out of the end of the barrel five or six inches when using the 130. It was pretty hot - I bought the .270 as a "hot-rod" kid because the kill power was slightly better than a 30-06 and it was a popular caliber with bear hunters in the 70s. I thought it was "cool" at the time, but I could barely afford to shoot the stupid thing and I never went bear hunting with it or any other gun. I had enough bad luck shooting a cousin's shotgun reloads on trap (an he was a pretty good reloader) that I don't think I would consider shooting an amature reloaded anything in a .270, 30-06, .357, etc, etc. (anything with a bore and some power).
It was not unusual to make 270s from 30-06 empties. Especially GI brass when it was available. Some times had to ream the neck thickness. Bad deal to keep straight. We even made 257, 7mm and others the same way. No big deal when shot in 30-06 except very in accurate like KEH says. That said:
Don't ever shoot some one else's re-loads. Bullets get mixed up, like a 7mm in a 270, Cases may be over sized to give too much head space etc.

The .270 is based on the .30-06 cartridge. And as others have mentioned, when I was first starting to reload for the .270 in 1973, I was given some fired .30-06 brass and tried to make some .270's. It worked, but you end up with a slightly shorter case neck, so it messed up your bullet seating depth and you had to tinker with that some. Really not worth the effort.
Shooting one of these would not have hurt you. It would have wobbled out the barrel and maybe some gas blow back.

Can be done as others have said but do it much and you hurt the barel big time. Sort of like running something with a bad wheel bearing if you do it for long you can mess up the hub same holds true to the barrel of your gun. Also shooting a 270 in that gun you would be luck to hit the broad side of a barn at 10 yards

The case will expand to 308 caliber and the neck will likley tear. Beware others reloads. It is so easy to forget what power is in the measure. I trained myself never to leave powder in a measure by throwing away whats in it if I do as a kind of punshment/ safety measure. My friend blew up a 45/70 marlin lever by putting 50 grains of a stick type pistol powder he had left in his measure that he thought was a rile powder. Since it was a stick type it looked to him like the rifle powder he had been using and had forgotten that he had loaded up some hot 45 colt loads in teh interem. Nearly cost him his hand, could have cost him his eyes or life.

I would find someone that reloads & have him pull the bullets & save the components. WD40 will not safely disable them. If you have a .270 Have him reload them with a known powder and a safe amount of it. I reload too & never hot load them in case someone else gets to use them . There is a starting load & a do not exceed load. When you get close to the do not exceed load, usually the accuracy gets poor so why do it. If you don't want them, send them to me & I will dispose of them properly. Don't throw them in the garbage. My E-mail is open.

Like I said earlier, I don't hobby with guns anymore (not anti-gun, still keep a shotgun in the house for protection, not anti-hunting either, just don't like cold weather but will eat others' venison or rabbit most willingly). I am recalling that in 1979 new .270 Remingtons were $1.00 per round. Consenquently, my .270 was fired by me maybe 50 times. I don't know what ammo costs today. That rifle had very little use when I sold it to an ex-brother-in-law. But it was a deadly accurate weapon even with my poor near-sighted vision. I can't hit the broadside of a barn with a handgun. I could bulls-eye at 50 yards with that .270. I think it had a Weaver Steel Light II 10x scope on it and pretty good mounts (don't remember what kind).

A 270 is just a necked down 30.06 you can safely shoot them in your 06 to fire form them back to 06. I once had a 35 Whalen which was an 06 fire formed up to 35 made all my ammo from 06 shells because 35 Whalen is a Wildcat cartridge.
I also have a 17/223 that is a 223 or 5.6 Military that is necked down to 17. You have to run them though the press then trim off the excess to work. They now make what is called a 17 rem. I can shoot these in my wildcat and they will fire form out to fit the shorter neck.
People have been doing this for many years to get what they wanted, most odd size cartridges were once wildcats.

The case length on a .270 is slightly longer than .30-'06 just for that reason: so a factory .270 won't chamber in a .30-'06. Shooting one those reloads in your '06 would probably not hurt your rifle, but the bullet would have gone wild of the target. If you shot several you might damage the barrel from gas shooting past the bullet.
The best thing to do with handloads of unknown origion is to pull the bullets, dump the powder on your grass (it's good fertilizer), and either give the components away or shoot up the primed cases and throw them out.

You don't need to do that if they've been properly sized, and you reload 270 anyhow.
Buy yourself a "bullet puller"

The idea that WD-40 sprayed on the outside of a cartridge will reliably kill the primer has been disproven. If you spray it directly on the inside of the primer it will kill it, but you have to pull the bullet to do that. At that point the components might as well be reused.

I shoot no ones reloads but my own. I can trust me, and my reloading ability. Who knows about the other guy.
