Considering an Artemis PP800R .22 cal (over the Diana "Bandit") purchase. Anyone have any thoughts on this pistol good/bad? Approx how many shots out of a "fill" in .22 cal? Any chronograph data you may have on a couple different pellets have would also be welcome. I know this is essentially a "regulated" Diana Bandit, so also asking if there is any wisdom in purchasing the Bandit, and then picking up a regulator separately? Lots of questions I know....but please feel free opine on any of this stuff.
