I know you are going to get advised to use Lil'Gun. There are several members here that have had good luck with it, enough that you may want to try it. Mine did not like it too much at all, I kept getting erratic results so I abandoned it for the 22 Hornet. Remember with a Hornet the case capacity is small so little increments in powder makes a big difference. You may want to try small pistol primers too, it works for some folks. I had best luck with it using W296, but nothing to write home about. I also determined that it did not like boat tailed bullets at all. I had not given up on it altogether, and was going to try some other powders and bullets. While thinking about what to do next I got this idea I wanted to shoot a 22 K Hornet. It is right now out being stubbed with a Douglas SS barrel for 22 K Hornet. Good Luck and Good Shooting
