Same setup as I have. I bought the GRS Dreamline instead of the Crown as I am not interested in a slug gun. I had a Crown and settled on the .22 Hades going about 885 fps which was crazy accurate and plenty for pesting . The Dreamline at 110 bar reg was shooting the .22 Hades at over 950 fps and I kept backing off the HS until I got great groups at 40 yards which wound up at 910 fps. I have left it there over the winter and when calm outside I hit everything I shoot at. I don’t exactly know how many shots I’m getting per fill but I’m thinking around 50+ which is good. I have thought of adding the bottle adapter and putting a 700 bottle on it like the Crown. But I like the look of the tube and I don’t need to. The only change I have made was putting the barrel band on it after I found it changed POI a couple of times. The band solved it. I’ll probably cut the stock out at the Reg adjustment and at the rear of the action to access the hammer spring. It’s really a beautiful gun .
