I love it! I've tried 5 diff ammo thru it. I've only found one that doesn't hold a pattern very well. Key is finding the ammo in a weight range you want to shoot/use, sight it in for that weight/ammo.... and buy yourself a well stocked supply of it so ya don't have to hunt for it later.

It is a fine shooter, and tons of fun! I definitely recommend it.
Gamo tells ya to put at least 100 rounds through it for break-in.... this is important before fine-tune sighting! But mine does hold very tight groups, and I am very pleased with it!
