I slightly recall an issue of undersized bullets being the culprit in another thread somewhere and I think it was everglades bullets. Try some other bullets that measure .224" and go from there.
I did, they varied from .223, .2235 and .224
Do you have a second powder scale that you can check your powder weights against?
Couldn't tell ya exactly what changed, but those same 'shelved' bullets shot just fine, w/zero keyholes.
I would say undersize is your issue. A 223 boatail is not likely to obturate to fill the bore like a flate base might. I would normally expect the bullets to run at size to slightly oversized like .224 to .225, not undersized. I would contact everglades and have them replaced.I did, they varied from .223, .2235 and .224
Ask anyway. The answer is always “no” if you never ask.
Well, on second thought I don’t know if I would want replacements...
At least we found the problem.
Systematically well done.
Still curious if weighing a sample will reveal any glaring discrepancies.
The OP’s load is fine, the twist is not the problem nor is the crown. The odd thing here is that only a few bullets seem to be keyholing, indicating that it is not the rifle. Shooting at a longer distance as suggested may help with the diagnosis.
Based on the limited information available my best guess is a problem with the bullets. Perhaps they were seconds/blems, have core/jacket issues, etc. But it’s just a guess as no one knows the real story yet......

I have a theory. A burr or rough spot in your barrel got smoothed out over the course of use. Before that it was damaging the jacket. Pushed a little harder and those bullets would have turned into a puff of smoke and never reached the target
