One thing to note is for reasons unknown, many manuals list max pressure loads below 50k CUP. SAAMI specs I guess, but not sure why since the 222 was introduced by Remington in a strong bolt gun.
Could be a reason the 221 Fireball often has loads surpassing the 222, at least in the lighter bullets.
Speed isn't the do-all, but it's nice to know if accuracy looks promising at "book" max loads, you can likely go beyond those safely.

Single shots and break opens, plus the petite Anschutz actions chambered in such leaves the 222 and 222 Mag. in SAAMI's "lite" status.
