Beautiful gun, looks just like mine!
Is that the Weihrauch 3-9x40 scope?
My HW95 came with the Weihrauch 3-9x40. At first it was an exercise in frustration. I went through various tins, trying to find that magic pellet and scope configuration. Some days the groups were great. Then the very next day the fliers came fast and furious no matter how I adjusted scope windage and elevation. This was worrisome, my HW30 and HW100 have been consistently accurate with most pellets. I began to think the HW95 was cursed. Was it the gun or the scope?
Being new to scopes and airguns in general it took some time to close on the solution. Thinking the scope was flawed I bought a Primary Arms red dot sight. Not only did this produce very consistent groups but it lightened the HW95 considerably. The problem with red dots is that you don't get a magnified view of what you're hitting. You need binoculars which adds more complexity. I almost stopped there. However, I knew that the problem was most likely with me and not with Weihrach. I forged ahead. After a bit of research I discovered parallax. Aha, another avenue of research! After a lot of trial and error and several tins, I found that the parallax markings on the scope were way off. I put a white sticky label on the scope and marked the correct parallax positions. I learned how to center my eye to the scope. Finally I was getting consistent 3/4 inch groups at 45 feet in my garage. YAY!
My HW100 has a Leupold Freedom 3-9x33 EFR Scope. It's 6 ounces lighter and smaller than the Weihrauch scope. Brightness is about the same. The Weihrauch feels more expansive, your eye can vary farther from the centerline than the Leupold and still get a decent picture. The tradeoff is that you have to pay more attention to centering your eye, moving the head side to side, up and down. The Leupold's narrower field of view inherently forces your eye to the correct position.
I like the Weihrauch 3-9x40 as much as the Leupold. Both are equally accurate once you understand how they work.
