I have only fired it at the 25 yard indoor range where I bought it. It key-holed round after round and even key-holed rounds after take down and reassembly. I was using a box of bulk ammo, CCI Blazers. I usually use bulk federal, but the Blazers were on sale for $18.99 for 525 rounds.

I plan to sight in the scope ate 50 yards this weekend with CCI Minimags. I'll give you an updated firing experience next week.
