Dr. Mike.. thank you for the help.. my guess was to start at 35.5 up to about 37.5…. This just confirms my guestimation.. Thanks again!…

Iraqvet, please update us with its performance. I’ve recently picked up RL16 and have loads in other calibers waiting to shoot. 22-250 is in my arsenal as well.
Mines - 1:12 twist. Currently running TAC and 40 gn vmax, but would like a bit more bullet… so interested in your results.
