Nice setup Carl! That's a neat little bunny buster! Hang onto that one!
I have a 2289G Backpacker I picked up 2 decades ago. Looks almost like yours, but with a green stock / forearm, and not as quiet or decked out. I just use the peep sight and it's dead on at 20 yards with 6 pumps. I was just shooting it the other day, still ripping through tin cans, original seals, valve, 2 decades later! No silencer, but it's pretty quiet. I always keep a couple pumps in it to seal the valve.
A Weirmuach HW50 .22 springer is somewhere in Germany, backordered... with my name on it.
These are pretty quiet without any suppression, moderate power, not 1,000 FPS, but 600 FPS or so (12 FPE), which is more than enough for 25 yard pest control / small game hunting. Always wanted one and I figured it was time. Nothing like a top quality, old school German springer, fine wood and deep blue steel. Spring is here, as are the destructive squirrels, rabbits and woodchucks and I have plenty of pellets!! It's relaxing on a sunny day to sit in the backyard with a cold beverage and quietly nail some tin cans. May as well do it with a top of the line airgun. Something to be said for pride of ownership. We only go this way once.
My son's Benjamin Trail XP Nitro piston .25 has a factory installed suppressor / shroud (?, whatever they call it!) and it works pretty slick, just a bit heavy. Yes, made in China, but I must admit I'm impressed. A quality built, accurate arm. Quiet, yet it hits about like a .22 short... perfect varmint gun if you have neighbors. This will take out coyote sized varmints. Cheap scope comes with it, but it works! The .25 is a serious step up from the .177 and .22 pellets. A little heavy for casual strolls in the woods, but to keep in the kitchen to protect your bird feeders or trash bins, it's perfect!
