I just posted this on the Ganyana thread but decided it needs a thread of it's own. I've tried to find the article several times in my boxes of old magazines but suddenly smartened up enough to check back issues online at riflemagazine.com . Here's what can happen when just a small brain bubble turns momentarily into a fart. Bob,
Yeah, you can cause gas "leaks" in about any action with the wrong ammo.
When I was living in Lander, Wyoming in the 1970's, the then-governor of the state blew up a Weatherby Mark V, which is pretty tough to do. He was taking part in the annual One-Shot Antelope Hunt with a .270 Weatherby Magnum, and chambered a .270 Winchester round. It blew the rifle apart in several ways, and injured him some. I don't think any action will stand up to a dumb-ass combination like that. The correct head-size at least minimizes gas leaks, but there's virtually nothing stopping the hot gas when it can go around a smaller case. JB, I saw a .270 win fired in a 7MM Rem Mag. Rifle was a 700. Shooter got plenty of gas and a few particles that drew a little blood. Rifle was fine and is still in use. Had a chrono set up and the bullet was going 1900 fps if my memory is correct. Probably a very good thing that the bullet was .007 smaller than the bore and that kept pressures lower than might have happened if the bullet fit the barrel. A kid and his dad learned to keep ammo separate and only one type on the bench. Back in 2001 Ross Seyfried wrote of a fellow that did just about the opposite; managed to chamber a S'em Mag in a .270 Weatherby chambered rifle. The unhappy result was barrel, action, bits of stock, scope and mounts being flung about with great enthusiasm. I went back into Rifle Magazine files and managed to find the article. Here is a picture of the result followed by a link to the article. Enjoy. Link to: How to Blow Up a Rifle

It's not a Mark V. P. O. Ackley blew up a Mouser with a load and then fired he same load in a Mark V, twice with no adverse effects.

I remember that.Quite a snafu.
The 280 Remington is overbore.
The 7 Rem Mag is over bore.

I have a Browning BLR in 270 that according to the previous owner has been fired, not once but multiple times with 308Win ammo. There is currently a 308 case stuck in the chamber, but the rifle didn't blow up and appears un damaged. I purchased the rifle to use in making a lamp for my hunting cabin. I had to agree to not resell the rifle or try to repair it. The dealer that had it was very concerned that the rifle had been damaged beyond repair, but I would bet that if I removed the stuck case, the rifle would be fine.

I've told this one before, but my son fired a .30/06 in a pre-64 M70 that had been re-chambered to .300 something-or-other but not marked. Bent the floorplate slightly and detached the extractor but no real damage to rifle or shooter.
Without shooting glasses, however, different story.

I've mentioned before that a buddy destroyed his Amish machine gun in .270 by reloading next to a window he had open to try loads through. He didn't notice that the breeze flipped the page of his manual from .270 Win to .270 W'by.

Wow!
Somewhere in the past, I've seen a list posted of lesser length but higher caliber rounds that will easily chamber, fire, and deliver various levels of excitement. Things like 30-30's in 270's and such.
Might be timely if someone could bring it up again.

Wife's cousin did a job on a Ruger77 chambered in 7mm mag.
A 270 win case is a poor substitute for a mag case. He had small cuts on his face and i thing it took a while for the feeling to come back in his left hand.
The rifle's action was fine but the floorplate was bent and the stock had a rather large crack in it.
He is not the sharpest knife in the drawer.

Years ago(when we were in our early 20's) we drove out to our buddy Kirk's ranch to visit and party.
It is early evening when a herd of whitetail start grazing out in a field. Really nice buck shows up....
Kirk isn't much of an hunter but borrowed my M70 300 Win to shoot the deer. Literally right off his front porch.
He liked the gun so I sold it to him. Next day he is still in a haze and takes the rifle out to shoot. Boom....WTF?!!!
Kirk was pissed for a second, spitting and picking brass shards out of his face. He thought I sold him a janky gun and I was initially dumbfounded, until I opened the bolt and there was a blowed up 270 WCF case in the chamber.
Gun was fine, Kirk's face was red for awhile.

I just read back through these posts and realized how many of these blowups/accidents involve the 270 Winchester in one way or another. Kind of surprising.
It is also surprising how much abuse that the modern rifle can take without having a catastrophic failure that results in serious injury or death. In the case of my BLR, the rifle didn't fail at all, but took the abuse repeatedly according to the previous owner. Of course the next shot could have scattered it over an acre or two and seriously injured the shooter.

25 years ago, the 25/06 had a reputation of blowing up with minimum loads(detonations). Whether or not the reputation was true, I can not say. I had a number of 25/06's used to detonate jack rabbits at the time, and never had a problem.
Minimum charges in a long case may be cause for alarm.

I've told this before, but I managed to fire a 270 in a Savage 110 in 7mag about 10 years ago. I didn't even know something was wrong until I opened the bolt.
A little brass was melted onto the bolt, but no damage to the rifle, and just a slight puff of wind on the face.

I have a Norma 270win case that was fired in a 7MM Rem Mag rifle[don't know the model] The case did not split but fireformed perfectly to the chamber. Primer shows that pressure was fairly skookum. Case is pinched a lot at the mouth because of the longer 270 case. It will not accept a 277 bullet. Came to me via my half witted BIL. He is not even in the drawer! Also had a friend complain the 22-250 shells I loaded for him would not fire. Turned out he was shooting his 7MM Mag. The rifles were the same model Parker hale 1200.

I heard of a guy firing 223 in a 6.8 AR15 awhile.
