I’d read some of @gimp reloading posts as well.

I’d just start 2 grains under what you currently shoot-and work up. Seat bullets at max mag length. Once at safe pressure, right velocity just shoot a 10 shot group and if at inch or under you’re good to go.

I'd be somewhat surprised if it groups 10 into under 1MOA. I have data from 33x 10 shot groups from various tikkas and exactly 1 of those groups came in under 1MOA. The average is 1.8
