How could you be sure ? When i test powders many times the results are opposite my expectations.
318... I like the accuracy and recoil from the .222. You can see your hits. With crows esp. I got to see the red mist and feathers.I’ve still got about 48# of AA2200 Data powder that I bought obviously a bunch of years back. It shoots outstanding in my deuce. As good as 322, 2015 Br., and 4198. The new production AA2200 would be high on my list to try as would AA2230 AA2460. Really the deuce is cheap to shoot, how many 22 grain charges can you get out of 7,000 gr.?
