Great little plinkers. I reload, using .32-20 brass - NO trimming needed. Depends on the gun - some do and some don't.
A buddy casts the lead bullets, and the cases last forever with the low pressure - so it's dirt cheap to load for. You do NOT need the gas sealing action to have fun. I enjoy popping soda cans and the steel .22 paddle targets.
