I've been quite pleased with my Gamo Shadow 1000.
1000 FPS velocities with regular .177 pellets, fiber optics sights which are the bees knees and way more accurate than I am these days.
Bought mine at Walmart for $129.99 or .95, who knows?
Anyway, they are a single stroke spring/air model with a 35-37 lb. cocking effort.
I'm serious about the accuracy. It is pinpoint out to 25-30 yards. It's probably good for 20-25 more yards further out, it's just my neighbors don't appreciate me shooting into their yards.
Mine absolutely loves the
Crossman Premier HP pellets (500 rd. pack) at Walmart. Also loves the
Gamo Raptors* and that other Gamo load that looks like a HP with a BB filled tip, can't recall the name of those at the moment. Anyway, these are all very accurate from this rifle.
And, the
Crossman pointed pellets (250 rd. pack) work great too. They are labeled as a "hunting" pellet.
Well, they all are, really.
*A note about the Gamo Raptors. These are very expensive Gold Plated Alloy Pellets that scream out of the barrel at 1250 FPS. They are always accompanied by a supersonic CRAACK! that sounds like a .22 LR bullet. Fair warning if you live in suburbia.
