Oh man, that's a good one, and when I say 'good' I mean bad. I hate taking ammo apart at the best of times but stuck in a rifle? Not ideal. I wonder if such a thing has ever gone badly? (Assuming it has at some stage.)
Good old YouTube though, makes fools of us all at some point I think.
I've not really had any bad ones I guess, just little annoying things, although I had a projectile stuck half way down the barrel of a .308 once. (Lack of sufficient powder). Ruined my day. I took it to a gunsmith and to this day wonder if the removal ruined the barrel. I ended up putting a Krieger barrel on it a year later...started clover-leafing where since the jammed projectile it had declined in accuracy.
That's about the worst malfunction, although there's been plenty of user-malfunctions! 😁
Yea.. I did it the cave man way.. it was dumb.
We've all done dumb things with firearms I guess, and in general. You got away with it and that's the most important thing. I'm too embarrassed to say the dumbest thing I've done with a firearm...it taught me a lesson though.
