Ok, get the eye-rolling over with right up front.
I'm not really a "gun person," although I like to shoot once in a while when I get a chance.
Years ago, I had the experience of accidentally discharging a pistol. No injury to property or person resulted, mostly because the bullet stopped and stuck halfway down the barrel. (And yes, this resulted in a somewhat awkward conversation/admission to my father, the owner of said pistol.)
Fast forward a bit. Using a tubing cutter, I managed to "disassemble" a rifle cartridge. Since I didn't care about "saving the brass," I figured this was a reasonably safe way to separate the powder from the bullet and render the cartridge pretty much inert. Basically, just gently cut the thing in half and dump out the powder.
So now I have an unloaded rifle and just the bare bullet that's supposed to be fired from this rifle. But the bullet won't fit in the barrel. It's in the right neighborhood, but if I wanted to push this thing the length of the barrel, I'd have to use a hammer.
Is this what should be expected, and if so, how much of an "interference fit" is there supposed to be? This would go a long way to explaining what happened with the pistol so many years ago. (Someone mentioned something about "old ammo," too.)
Thanks in advance.
