I’ve seen more reports of ELD m’s going poof than any other bullet. I’ve had issues with the 52’s.
When I contacted Hornady 300,000 RPM’s was their max.
I wouldn’t be too worried about it. If for some reason you have issues you can always swap to Berger, Barnes, Sierra, etc. Even if you are around 3050 FPS you are still less than 315k RPM’s. I would go 1-8 or 1-7.5 on your next barrel though.
I’ve always wondered what the best number of grooves is for bullets staying together. I have never came across a study on it.

Blowing up bullets is more a result of the grooves and bore diameter.
Iv got a lot of rounds through 7 twist 6 and 22 cal with zero issues using 6 groove .219/.237 bore barrels.
