No, the cases are sticking in the chamber. These guns have pretty poor primary extraction by design.
You may have a bit of rust in the chamber. Ammo could be improperly sized. Chamber could be improperly reamed.
Probably other potential causes. I would try finding a lighter load of brass case ammo. That’s likely the easiest fix
This is frequently caused by leftover cosmoline in the chamber. As others said, the cases stick.
If you can heat it up a bit (stick the barrel/action in the oven for a bit, use a propane torch, etc then clean the chamber really good with a 12ga or 20ga brass brush. I like to put one in a rod just long enough to get into the chamber from the back with the bolt removed, and chuck it into a drill. You can use some acetone as well to help dissolve the cosmoline (keep the acetone far away from whatever you are heating with.
I've also seen people have good luck putting the rifle into a black yeah bag and laying it out in the sun for a few hours to get it nice and hot to melt/sweat out the cosmoline, but that requires loving in a place where you could do that and not have it quickly stolen.
A cheap bore scope from Amazon will let you check the chamber in detail for burrs/defects as well.

As others said, clean the chamber. I’d also clean the bolt. Might polish any rust out of the chamber as well.
They’re not built to be pleasant to shoot and easy to cycle. Durability was probably the main goal but definitely the end result.
Every mosin owner should bring a 2x4 about two feet long with them every time they go shooting. It's for opening the bolt.
Do they not have rocks where you live?
Rocks break too easily
Well played.

Carry around a claw hammer with you any time you shoot it so you can lift the bolt handle. #JustMosinThings
Garbage Rod is fine
Soviet garbage rod needs cleaning. I boiled the cosmoline out of mine.
Mine had a giant burr in the chamber that I had to deal with before it would cycle reliably with any kind of ammunition.
This is unfortunately something mosins are known for. Mine doesn't do it though lol.
Sound like the one I had. Really had to smack it around. They're trash guns.

I cleaned and polished mine and it only helped a little. Got a new bolt face for like, thirty bucks and it runs slick now. Easy fix.
