This rifle is “solid as a rock” built with quality materials and fashioned with old world workmanship. It yearns to be taken on the hunt and is certainly capable of delivering the quarry. This is not a target gun, it is a hunting gun. The cocking force is specified to be 46 lbs.; mine weighed-in at 50 lbs. The HW90 is a heavy air rifle weighing in at 9 lbs without a scope. This is not the gun I choose for a day of target shooting or plinking. This is the gun I choose for hiding or stalking, when it will be cocked for hours. My HW90 is pushing the .22 caliber, 18 grain pellet out of the barrel at 24 ft/lbs which results in a substantial recoil. This is not a fun gun, it is an excellent hunting gun and I can whole heartedly recommend the HW90 for this purpose.

That's correct, it has the Theoben Gas Ram System and you can adjust the power if you have the right tools. This is a quote from Guy who is another HW90 owner: "It would be really nice to be able to obtain the proper pump or even just the valve adapter from PA, instead of trying to locate what I need through European websites. As of right now, I have no idea how much pressure is in my gas piston and no way of adjusting it on my own." Can you imagine adjusting your PCP with no idea what the pressure is and no way of recharging it ? The HW90 is sold as a magnum powered, gas ram air rifle and it is. If you reduce the cocking force you loose power at the muzzle and I bought the HW90 specifically for that power. This is not a fun gun, it is an excellent hunting gun. You can hide or stalk the quarry for hours with no worries about the gun being cocked for such a long period of time."led_lobber86"im pretty shure the hw90 has the theoben gasram system that lets you adjust the power and thereby the force needed to coch the gun
