What's up guys? Long time airgunner here, first time big bore owner... Recently purchased this Ataman M2R .357 (refurbished) from PA. The deal was way too good to pass up. Even after the discounted price, I was able to apply the 10% off coupon. I shot it for the first time today and it shoots great in terms of accuracy, but velocities range from 750-800... I paid for the 10 for 10, and noticed velocities we're low on the card I received with the rifle. Checked it myself in the interest of "trust but verify", and I got roughly the same velocities as the tester. All of the other videos I've seen of this gun are shooting in the upper 800s. Anyone else had this gun, and possibly had this issue? I'm hoping either the hammer spring is tired, or there's possibly a restrictor somewhere. There appears to be a small hole with a recessed screw under the stock, but I don't want to just go jamming allens in there and turning stuff without knowing what it's doing... Really hoping I didn't get a lemon either. It was a "certified refurbished", but who knows how much that's worth. Aesthetically the rifle is beautiful. No blemishes or flaws I can really see. Anyway, if someone could provide some insight I'd really appreciate it!! Thanks guys.
