I've seen that happen with 17 HMR and 243 WSSM and the only thing I can sum up is just flat out bad brass and the WSSM brass was almost grainy looking

What type ammo and how old is it?
Have been more than a few batches over the years with this defect, it's probably kicked off a half dozen recalls over the years from at least half the flavors. Those shoulders are thin. Hm2 and wsm will on occasion do it as well.
Last recall batch was winchester... I shot my brick before the recall kicked off... messy but never any problems other than chamber grit.

over size chamber
metallurgy on the brass too brittle to expand
undersize brass
You maybe forced to keep the chamber clean and use the ammo up.

On the clean chamber front that's worth keeping an eye on. Wife gets these q tips with a long stick, I push them up in the chamber and get a good soak then get in nice and clean. 17s all have chamber sensitivity issues. Was home today and checked zeros on all of mine, one 17hm2 was filthy as was a hmr, my 17 wsm was looking like a stove pipe less than 100 rounds since last cleaning. Kinds goes with the territory, but ocd chamber cleaning definitely helps.
I'd hate to give bad advice so will frame it this way, some folks have lower risk aversion than others. If you double masked in the car by yourself I'd say don't shoot them. If you ride a road motorcycle without a helmet and eat food past the expiration date... you will be just fine shooting them.
During covid a buddy found out he had bought a case of recalled 17hmr ammo, being in Alaska they sent him money in lieu of shipping the recalled ammo back for like exchange. He wasn't sure the best way to dispose of it, and my services were volunteered. They shot great with the occasional one going bang with a decent flier and the use of a decent little pry bar to remove the offending brass. Different risk aversion different response, personally I'd throw on a set of saftey glasses and let it ride.

I had a pest on top of a power pole today
I got the 17 hmr and tried to load a round (bolt action)
I could not get it to chamber
On inspection I found a fired brass in chamber
The round I unsuccessfully tried to load was pressing into the stuck chamber brass
I stopped and cleared the chamber and noticed the round I attempted to load pressed the bullet completely inside the shell
I could see the bullet tip(barely) and powder in the cartridge
Out of curiosity I orientated the barrel up and hand fed the cartridge into the barrel
I fired at my pest about 65 yards away and it dropped as it always does
So this makes me question all the time I spend on bullet seating depth
I realize this is a 17 hmr but I could barely see the bullet as I had jammed the bullet inside the shell
Any explanation?
