Buckshot Shells Expanding In Magazine?

[rsrocket1]

Its the construction of the hull. Thin is in...cost less to make...costs less to buy.

I would not be surprised (from the pics) if the OP finds the shortening of the shell to be from the hull being pushed into the base.

Still, shells compressed in a mag tube for almost a year without being moved? That is asking quite a bit.

I wouldn't be surprised if they didn't "tent" if left in a box or out in the open

Winchester Super X and Universal hull have uber thin walls and do not hold a crimp very well under pressure. Try Remington Gun Clubs. They're almost as cheap but the walls are thicker and they tend to hold a crimp better.

Not gonna find Gun Clubs in buckshot.

I've bought Super X target loads that had this issue out of the box. They wouldn't cycle in my wife's semi auto and I could just barely jam them into my break action.

For a defensive load, I wouldn't trust my life to Super X.

I've had the same intermittent issue in a bird gun with Winchester AA loads straight out of the box. Upon inspection, it was indeed a manufacturing and quality issue.

I don't buy those shells anymore. So much for AA being great.

Thanks for all the input everyone. I located the rest of the ammo I bought at that time and there were some other shells like that in the box. Some look like I may have rotated them out, but others did not (memory not what it used to be). Either way, it sounds like this Winchester ammo is cheaply constructed and doesn't have a long shelf life. Going to go shopping for some better rounds this week. I know I've kept shells in the tube longer than that before, but lesson learned to check/rotate them more frequently as well.

Also attaching a picture of what these shells look like brand new for reader comparison.

My 10 gauge buck shot don't do that in their magazine
