I only shoot 22 ammo in my Pardini SP pistol. For practice, I like Aguila SV. For matches I shoot Eley Target Rifle or Target Pistol, and have been trying out some new Federal Gold Medal we got via the CMP. This gun didn't like Federal 711B when I tried some a few years ago but this new batch is excellent. Other good brands I've used are Wolf and RWS. Wolf is the softest recoiling ammo I've tried, but won't cycle the action in a number of target pistols we've tried it in.
