Start at 29.7gr lvr, cci 41 primer, starline brass. Load them as long as possible. I've pushed up to 30.8 and saw nothing troubling indicating over pressure in 2x criterion barrels. They were pretty sensitive to jump though, if you get a chance try the otm hybrid. Load data is almost the same, but better accuracy in my experience (being limited to 2.3" due to magazine)
