I have a .25 Hatsan Model 95 Gas ram. After not being able to group shots as well as I wanted, I acquired a .22 D350 Gas Ram. The Hatsan, which I thought was a powerful rife, is mere a pee shooter by comparison. In terms of power -- not even close. The 95 gently pushes .25 pellets across my 35 yard range and groups on average ~2". The D350 basically sounds like a .22 firearm. So far, the recoil has simply ruined the innards of the scope that happily sat on the 95 for years. It then somehow managed to snap the metal peep sight clean off (which I never use). I replaced the scope using a Diana recoil absorbing spring mount, which seems like it works as intended. I think this is a must have with this gun. This thing shoots H&N .217 slugs as well as any other pellet I have. It's about as long as a fishing rod, I wish it were more quiet and it's a mother to cock. But I shoot groups that are far tighter, and the power is wow. There ya have it. The D350 is a good gun!
