Hornady 9th vs 10th reloading manuals?

What was added? Specifically, I'm curious if anything was added on 300 blackout, 450 bushmaster and 6.5 grendel. I can buy the 9th edition for 1/2 price of the 10th. Just curious if it's worth the extra cost. Thanks!

i would have to say no.

i bought the 4th ed in 1993 and i used it until i got the 8th ed in 2012? i think. i only got it because i am using a 6.5 creedmoor. i still use the 4th ed tho.
