I think I'll initially test it with the .22 power loads. I would prefer not to modify the existing .22LR chamber, so I'm thinking that for the .25 caliber power loads, I'll create a sleeve that fits over the barrel's breech shank which also extends another half inch or so and that sleeve will be chambered for the .25 caliber power load. Ideally, this would be threaded and I would have an identical one for .22 caliber power loads so I could make direct comparisons, but I have not gotten to the point where I'm comfortable enough with my mini-lathe to try single point threading on it. So, for initial testing, I'll probably just make a slam-fire "receiver" for it. I'm not concerned with the inaccuracy that a slam fire design will give me since this is going to just be a hard mounted test barrel and the only accuracy it needs is to NOT hit the chrony from 10 ft or so. :)
