    Was gonna say, can’t fit a .270 Win in a .243 Win chamber.

    An 8MM Mauser cartridge will chamber in a .30-06, and if it happens to be a Mauser action the controlled round feed extractor will hold the primer close enough to the bolt face to fire the cartridge.  Pushing a .323 bullet down a .308 bore can get exciting,  P.O. Ackley did a lot experimentation with intentionally firing oversized projectiles after WW II when a few rifles got blown up supposedly by firing battlefield pickup 8MM ammo in -06 rifles.  He determined that if the case neck could expand sufficiently to release the bullet, the oversized bullet would swage down and exit the barrel with little ort no damage.  A case jammed tight into the chamber would cause a blowup.

    Whatever that cartridge was that blew it up, that guy is one very lucky shooter. In Disbelief animated emoticon  That rifle disassembled itself into LOTS of pieces. He's very lucky to have all his bits and pieces intact!
    Looking at the case dimensions of the .25-06 vs. .270 Win. I'm more than a little amazed that he could stuff a .270 Win. in the .25-06 chamber. The cartridges are dimensionally almost twins with the neck diameter of the .270 being larger in diameter and the overall length of the .270 case being longer being the difference. The difference in neck diameters being only 0.010 it could be possible, though. Scary!

    Whatever that cartridge was, it sure did make a mess of a nice rifle.

    Well, on this forum that's ludicrous to say it was a .270. Everybody here knows a .270 can't blow anything up! According to forum lore the bullets lucky to get out of the barrel much less have enough pressure to blow anything up!

    One of the popular scenarios of this is the .308 Win. in a .25-06. I think I've also heard of a .308 in a 6mm Remington. I could also easily see a .308 in a .270. But no way do I believe a .270 in a .25-06 and especially a .270 in a .243.

    Not with that attitude, you can’t.

    This looks like a barrel obstruction near the chamber. Powder missing in a cartridge would leave a bullet not far from the chamber. An inattentive shooter could chamber another round with this result. It would be interesting to get that case out and find out what is in the barrel considering all the pressure went through the action. 

    There's really not a lot of info given on the shooter or the gun.

    I had some MILSURPS on the range years ago. I believe it was a 6.5X55 Swedish and a K-31 Swiss 7.5X55 ammo I got mixed up on the bench and didn't realize it until I started closing the bolt.

    Best to put away ammo when you are done with it and only have the proper caliber cartridges within reach when you have multiple ones.

    Some calibers at first glance can be mistaken. Like .303 British, 7.62X54R and 8X56R. I guess 30-06 and 8mm too. Although I only own a 8mm not a 30-06.

    30-30 and .32 Win Spl? 

    9X18 MAK and 9X19 Luger.

    Some may or may not chamber completely, but sure can cause a disruption in your shootin fun.

    The rifle self destructed in an act of suicide because it could not live with the indignation of having had a .270 cartridge stuffed into its chamber...

    That is the exact word I was going to use. A small bomb went off in his hands and face and he apparently came away unharmed. It is truly a miracle.

    When I was a kid, I loaded a .308 Win cartridge in the tube of my dad’s .30-30 Winchester lever action rifle.

    Fortunately and unfortunately, it wouldn’t eject from the tube and enter the chamber. 

    It took a trip to the local gunsmith.

    You weren’t anywhere in the TX hill country at that point, were you?  I remember talking to a gunsmith in that area a long time ago bitching about having to completely disassemble the mag tube on a Winchester 30-30 to get a 308 out of the tube.

    Ha!  Nope.
