I have a load for my Tikka H.B. that is a bit out of the ordinary but is the best shooter in this gun. R-P cases, R6 1/2 primers,18.1 grains I4227 powder over 40 gr. Vmax bullets. Have never chronographed it since I only shoot it at paper.

Normally you don't see a powder this fast mentioned for the .222.
