I work at the place I'm buying and transfering from, so price is a bit lower than normal. We've been shooting it at the store; performance is great, on par with the best rimfire cans I've shot through. Running on a semi-auto is a little disapointing for any can, there's noise from the blow-back action. Still fun, and boltguns are sick quiet with sub-sonics. I'm going to thread every 22LR I own, plus my 22K-hornet (the sparrow is rated for small centerfire 22cals, ie 5.7x28, 22horn, 218bee, etc.). The best thing about it is being able to take it apart in 15sec, with no tools, and the baffles/main body are one machined piece.
