With a buttload of crimp??I never say never but, how does a .221 bullet stay in a case that is sized for a .223 bullet? There has to be neck tension to keep the bullet in the case.

Nope. Crimp can never make up for lack of neck tension. The bullet will be wobbly in the case and it will be immediately apparrent to the factory and the end user. Even the russkies have to have basic QC....
Hah, I said "never"....
But you can verify my statement for yourself by crimping a normal bullet into a fired, unsized case. It just does not work...
Wouldn't that depend on the type of crimp? Basic taper crimp, it makes sense that it wouldn't hold. But with a collet style "factory crimp" like the Lee FCD dies for pistols have, I can see it working.

The same way I can get a .427 bullet to stay in a caseing sized to .430. Cannalure crimp.
Me too. This whole thread has me scratching my head.
A 1X7 223 barrel stabilizes everything. I have never seen a dirty barrel cause keyholing. Never a dinged muzzle. Certainly never a magazine.
You could always measure your bullets to see if they are undersize, but I don't see how that could cause keyholing either.
Something is happening that is a mystery to me.
Look, the easiest thing to rule out is the ammo.
Go grab a box of quality factory loads by a reputable company (we are not considering steel cased Russian ammo *reputable* for this experiment).
A different brand of ammo, key-holing or not, will tell you LOADS more than any internet gun-nut's suggestion can at this point. Otherwise, you are just guessing... and whatever you decide to try is going to cost more than trying different ammo first (which is really NO COST because you always need more ammo anyways).
Yes, I heard you claim you've never had a problem before with the ammo you are using - multiple times actually. Same lot or not, the ammunition is the most likely culprit at this juncture. After all, the Russians are not known for their precision or attention to detail.
Is your brrel nut still tight?
Bullets loaded into 223 Rem are, largely, 0.224" in diameter. I'd flinch if I discovered commercial ammo manufacturers sizing necks with less than 0.008" constriction and unable to achieve purchase on a 0.218" bullet. I don't, but they likely do.
This thread is stocked with wild guesses more so than usual. Cleaning it is particularly entertaining.
OP: have you spun this bore by hand, to know it is a 1 in 7"?
i had a friend of mine not long ago complain about the same thing. spent hours trying to find something wrong with the gun. just to find out it was the ammo he was useing. changed ammo and the problem was fixed.
I do plan on switching up some ammo to see if it works but idk why it would randomly start right now. Who knows
