I have a 222 Tikka with a 1-8 barrel. I regularly ( well, in the summer) use 55g for bunnies ( 19.8g N120) and for heavier bullets, 69g etc switch to IMR8208. Use loads from Hodgdons data - I cant remember off hand. With a can, Its a lot quieter than the 223, so more useful around farms and neighbours.
