I have the Dreamline GRS as well. I shoot Hades in mine as well. No need to use anything else they are that good. The Dreamline is a wonderful platform with the adjusting knob you can dial it up or down to suite different conditions. It isn’t too heavy like a lot of air rifles either. I just got the New DRS .22 x 600mm for a dedicated Heavy Pellet slinger and it shoots the JSB 28 grn Monsters fantastic. I restocked it myself in a GRS inspired stock and I am very happy with it but I’m not selling the Dreamline any time soon.
