So my brother in law showed me some pictures of a blowed up rifel he said the guy put a 308 round in a 270 ? Will a 308 chamber in a 270 ?

[lead-1]

My guess is that a .308 will chamber in a .270 since the .270 is a longer case like a .30-06 and has the same case head diameter as a .308.

Edit to add, I also don't think anything good could come of making that mistake.

Knew a man who put a .308 winchester through a 25-06 rifle survived . A brother in law put a .308 winchester through a model of 1917 chambered in 264 win. mag. parts of stock and small parts on bolt and ejector did not , bullet stopped half way down barrel as brass could not seal chamber , rifle has been rebuilt and the gunsmith I gave it to has the bullet , nice and long.

[Winger Ed.]

The .308 is short enough, that it probably did do just that.

Years ago, I was talking to a guy who had a .357 lever gun and told about a fella he went shooting with.
They got to talking and his buddy liked shooting the .357 and figured it'd be a lot cheaper to shoot them
in his .30-30 if they would fit in the loading gate & magazine tube.

Never heard a range report,
but he asked the fella what he thought was going to happen when that .38 cal. bullet tried to get down through that .30 cal barrel.

Like most of you, I have found the odd cartridge at the range that was fired in the wrong chamber. 308's in 30-06's. 300 Winchesters fired in 300 Weatherby's. Stuff like that. Luckily there are only a few that will fit in the wrong chamber that are dangerous. I guess a 270 has enough taper that the straighter 308 would wedge itself in the chamber tight enough to fire.

[Thin Man]

This happens with handguns as well. A while back a fellow brought us his new 9mm pistol that was acting funny. It didn't always fire the round in the chamber, and when it did the brass looked really odd when it came out of the chamber. He had just bought the pistol from a shop that had sample pistols in the front counter. He looked them over and decided to buy a 9mm. (This same model was also offered in .40 S&W.) The clerk went to the stock room to find him a "new in the box" 9mm but handed him a .40 W&S caliber model by mistake. They completed the 4473 form and all was well until the new owner tried to fire the pistol. When I told him what had happened he got excited and headed back to the seller's store. Wish I could relate how this transaction ended but the buyer never came back to us.

I saw a nice old Sako blown up ! same senairo 308 in a 270

[KCSO]

Yes it will! I had to scrap a Remington 760 pump gun that was destroyed like this. Fellow had two rifles just alike and got his son's by mistake...kaboom!

[nelsonted1]

I was at my first high power match when a guy blew up his brothers m1a. The rifle let loose with a horrible bang. The guy stood the with the rifle to his shoulder, right hand holding the stock straight up and the forearm split in a Y all the way to the trigger guard. The barrel made.two flips in the air landing next to him. ..... The gunsmith who built his brother his new M1a drove out to see the guys reloading room. A can of aa5 was on the bench. Turned out the put 42/grains in a .308. He was.badly shook up and his forehead bled a lot but no real damage to.him. We all relearned a.lot that day.

[Texas by God]

My First brother in law grabbed a .243 round left on the bench by my brother and fired it through his own .270 Ruger. The neck blew off, played sabot, and both it and bullet together landed in the group on the target.
If you are lucky; poop will do for brains......

This is true.
I've come to realize the average person watches wrestling on Saturday night TV, and thinks its real.

You don't hear about it much any more, I think they've flushed out or been retired by now,
but you used to hear about people loading .357Mags in old .38Spec. revolvers that had straight through bored cylinders.

Without the chamber shoulder in newer ones, the .357s would fit, and sometimes blew it apart.

[smithnframe]

I saw a Ruger 77 that the same thing happened in. Except.......the barrel and action were ok. The bolt was in need of replacement/repair though!

[marek313]

It happens all the time I'm sure whether guys admit to it or not is another story. Just last month I had a guy next to me shoot 40s in his 45acp 1911. To his defense when he went to buy 3 boxes of 45acp, clerk got him 2 boxes of 45acp and one of 40S&W. I know its still the shooters responsibility to double check everything but things happen. There was a picture of 16" .223 barrel with about half dozen .308 projectiles lined up like a train because 300AAC will chamber in .223 so be careful thats all.

[Walks]

Went Dove Hunting with 2 friends years back. Roger shot a 28ga O/U, Ken shot 20ga Rem 1100 and Me, and old Mod 12 20ga.

Some How Ken got a 28ga shell in his pouch. Blew off his left thumb half off.
Ken thought he had fired all three shells, only fired 2 third one was a 28ga. It's rim caught on the end of the chamber stopping it in the bbl. A 20ga went into the chamber.

BOOM

No matter how hot the action is on a Dove Shoot. Always IDENTIFY the shells going into your gun.

20ga are YELLOW
28ga are RED

[nelsonted1]

Dad was deathly afraid of us getting a 16 gauge because of the chance of us sliding in the wrong shell. He said a 20 gauge is so different from a 12 gauge one can feel it but probably not a 16. Then, one day we had a friend give my brother and I a 16 gauge. We had to sell it. We didn't mind since Dad and Grandpa were people we listened to always. They didn't say much but when they vetoed something we listened. ..........
A perfect example was hearing us talking about hanging a dead calf from the freeway bridge on halloween. He got us to hang a skinned out raccoon instead. Shazzam! A highway cop was under the bridge cutting down a calf when we started lowering the raccoon. All we could say after the roll through the feed grinder with the highway cops for three hours was the blind luck having Dad hear us.

I have both a 16 gauge and a 12 gauge....you can't always go by color code of the shell.

I have purple and red 16 gauge....but I also have green and RED 12 gauge.

I have to be VERY careful...a 16 will slip into the barrel in front of a 12 also.

[dverna]

My buddy told me a guy dropped a 28 ga shell into a 20 ga. When it did not fire he dropped in a 20 ga. Blew a Beretta over/under apart and he needed to go to emergency. Not pretty and the gun was totaled.

[abunaitoo]

Yes. It will chamber.
If it is a strong action, it might hold together.
We have had a few rifles blow up at the range.
Less that didn't.
.308 in a .270.
Not good.
Every once in a while, I find some .308 that have been fired through a .30-06.
Makes a nice straight case with a slight crimp at the opening.

that'll buff out.

[Walks]

It is if all of you are using Win AA cases.

And yes a .308 will fit into a .270 Chamber. Took my rem 700 bolt apart to try it.

If some of these folks keep working on it maybe by getting a .50AE or .300WSM into a .223 or something---
they'll eventually find a cure for stupid.

[Freischütz]

A number of years ago a friend did this with an FN commercial Mauser. Broke one locking lug completely off.

[Geezer in NH]

The problem solved itself. Idiot got a dose of reality.

[nun2kute]

I will be the first to admit I am far from the brightest bulb in the package, but cummaughan ! Who am I supposed to blame this on ? Caliber stenciled on the barrel !!! and printed on the Box !!! It went past TWO PPL and got to the range.

Hope I haven't jinxed myself by laughing at some of these stories.

[mjwcaster]

The caliber isn’t always on the barrel.
My lone wolf 9mm conversion barrel for my Glock 22 is not marked.
I wish it was.

And sometimes the ammo is in the wrong box, for whatever reason.

Which is why I try and teach to check the box and head stamp.

I had a student some years ago ask if he could bring out another pistol in the second day of shooting, he was getting misfires.

After the qualification shoot we would have a fun shoot. He brought out his 40cal, and I looked over and saw a box of 40sw.

I was working with another student, but keep watch out of the corner of my eye.
First round failed to fire so I check it out.
No firing pin strike on the 9mm cartridge.
The whole box was filled with 9mm parabellum.
How and why I have no idea, not sure where the ammo came from.

I haven’t shot a 9mm in a 40, but that is only because a 9mm Kurtz will not stay in a 40cal Glock mag.

Broke my own ‘one gun one ammo’ rule one day, shooting 380 and 40 that day.
If I had been shooting 9mm para and 40 it would be my expanded 9mm in my teaching collection instead of my partners.

That is probably the most common confused cartridge.

Heck, the day I tried to load 380acp in a 40sw mag, I also ended up with the wrong Glock 22 in my holster.
Both guns were identical, I only noticed after we returned from the rifle range because of the condition of the pistol, loaded vs unloaded I think, not sure but something wasn’t as I expected and I figured out I had another shooters gun.

And no we were not chemically impaired, I was just naturally dumb that day.

Didn't have a problem, but was shooting two rifles from a bench one afternoon, a .303 Savage and a .32 Winchester Special. Not sure if one would even chamber in the other, but it dawned on me while picking up brass how similar the two are. I should probably be more careful.

[LawrenceA]

Years ago I saw photos of the results of firing a 308 in a 270. It was used as an ad for Ruger.
In this case the cartridge fired, the bullet exited the barrel.
The case separated split the stock blew the floorplate from the action.
The story went on that the shooter was fine and empty case extracted but was a little stiff.
The case was shown and had fireformed to part way along the shoulder from memory

[nun2kute]

I have found empties that appear to have been fired in the wrong chamber, but have never actually heard (until now) or witnesses the event. But I will be studious in learning from someone else's mistakes. Thanks for the Education.

[kevin c]

Joe Public uses our range, as do police agencies and private instructors. Not at all uncommon for me to find 9mm brass shot in 40 S&W chambers.

I also remember a front desk guy at an indoor range running into the firing line after he realized that the guy who just bought a box of 9mm had previously rented a forty. He was too late. Fortunately, no injuries to the shooter or gun, just keyholed targets and mangled brass.
