Yesterday afternoon some friends and I went shooting .22's.
I had my carry gun with me so I figured
I'd rotate out my carry ammo w/fresh stuff.
I normally spend alot of time in the woods so I
keep one round of ratshot in the cylinder. I've
had to use it a few times for copperheads.
So the round of snakeshot has been in the wheelgun
for months. Here is the problem...I pulled the trigger and
the cylinder was LOCKED UP!!
I was floored.  My constant carry gun was jammed and I didn't
even know it! Holy shit. I just became deceased!

So, word to the wise. If you carry ratshot, check it frequently.
You can see in the pic that the "cup" had worked its
way forward where it hit the forcing cone, jamming the
little wheelgun tight. I was able to push the shot cup back into its
fully seated position without a problem, but the lesson could have been
very very expensive. Same thing can and will happen with non-roll crimped SWC ammo.
ETA: yes, my carry gun is rather nasty. The paint on my car is ugly also,
but its probably in better mechanical shape than 99% of cars on the road.

Those the plastic shot cups from the CCI line of shells?


Stands to reason that they haven't figured out a way to crimp the shell without harming the plastic shot cup.

Yes, its CCI.

Contact them! They can never fix what they don't know about.

I hand loaded shot shells some years ago using Speer components and a heavy crimp was recommended and worked without any problem.

I haven't had any problems with the shot shells yet.
however, I have had a problem with the crimp on FMJ rounds.
had a 9 mm bullet pop out of the shell while loading my p94, got gun powder all over the place.
seems like the aluminum casings just don't have the loadedand carryed  life span that brass casings do.
the CCI rounds would start coming apart after about 2 months of carry.
Brass will start to move around at about 7-8 months of carry.
