Speaking only for myself,
If I’m choosing a 22 auto loader then I’m goin for whatever loads cycle most reliably.
In my case, my g19 AA22 conversion kit is very reliable with CCI mini mags. If I keep it relatively clean and oiled.
As for velocity, copper/lead, grain weights, hollow point or not, doesn’t matter as I see it. As long as it goes bang. Somebody wiser said something along the lines of “know what the limitations of your gear”
Whatever load works, I’m betting it could prove to be quite the eye irritant.
