    End result of a .30 caliber projectile after being "extruded" through a .223 chamber/barrel.

    AKA Very Bad Day

    OK, thanks, but the proportions seem off to me. Could it be more then one projectile in that pile up? There are two cases.


    Edit: This pic puts it in perspective for me.... I see it now! :innocent0

    Moral of the story: Store your ammo in the proper container. Never mix blanks with live ammo. Always check what you are loading into a magazine. Only load the weapons with the proper ammo.

    Nice list! Adding to it is to be sure you keep ammo away from your bench when doing anything with a gun. Also, be sure each and every one of those snap caps really are snap caps when you're loading a mag or gun to do function checks at the bench!

    I was on a range in Montana checking zeros before an elk hunt. Two other guys were there and wound up mixing up .300WM and .338WM. The guy was having trouble chambering the cartridge, I told him to stop because something was wrong. Thank goodness he listened.
    My buddy and I shot and went to camp. Later the Guide told us about the mix-up. Seem like one guy reloaded both calibers and scooped them off the reloading bench and mixed them up when putting the cartridges in the boxes.

    Good luck

    .223 in an AK 74....... Had it actually struck the primer, I might not be here today.

    Why?

    Smaller in a larger chamber is not a huge deal.

    Shoving too big in a smaller chamber can be a HUGE deal.

    My son in law borrowed my Sig229 40 and loaded it with 9mm Mostly jam issues before i found out what he did , thank goodness no one was hurt.

    How would they be hurt?

    Several people on this thread have mentioned firing or trying to fire small rounds without any problems. Even with the rounds fired.

    The problem is the case is unsupported and could possibly rupture.

    Another problem is putting 3" shotgun shells in a shorter chamber, it causes a big pressure increase when the lead and wads have to be forced past the crimp which is now in the barrel instead of in the chamber where it has space to get out of the way.

    It does rupture. At a fairly low pressure, and the rest of the powder burn goes Pffft.

    9 in a 40 or 40 in a 45 is not a big deal. Not to do it on purpose, but if it happens, you can't reload the case is the big thing. :)

    Bigger (3" is bigger than .275") is ALWAYS a big deal.

    The P-64 is chambered for 9x18mm Makarov but will safely chamber and fire .380 rounds. I have read that this was done by design so it could fire captured allied ammunition if necessary. I do not own anything in .380 so mixing up the rounds is not an issue.

    I don't think it matters. One shouldn't become complacent. One should always check the rounds being loaded and fired.
