I’m building a 300 prc, I’m planning on a 22” barrel. The question being twist rate, will a 1-10 twist barrel work with 212 grain hornady eldx? Also will it handle 225 grain as well......thank you for your time.

1/10 twist is very standard for 3p cal heavy bullets. It will work fine.
You will see most guys running rh heavies in PRC using a 9.4 twist though.
1:10 should be okay up to 230gr. You may run into issues at low elevation on cold days with 230gr pills.
1:9 will handle everything up to the 250 A-tip, 1:8.5 or 1:8 will maximize BC on the 225-250gr stuff.
I went with a 1:9 and I'd guess most are building PRCs with 8-9 twists.
