Quit Screwing Around: Lets see those SPRINGER GROUPS

35 yards, kneeling off my deck, 5 shots, factory iron signts Winchester 1100SS using Crossman dome copper plated pellets. I nee to spend more time behind the trigger, this sucks. Normally with my M4's I can do a 1-1.25" group at 50 yards.

New Walther Terrus .177 - I am using Sovereign Rangemaster 8.4 Grain at 28 yards resting on a shooting bag, the first image is only with 25 or so pellets through the gun and me getting used to holding the gun correctly, so excuse the few flyers -The gun has exciting potential...The second image is after around 100 pellets through the gun...Starting to tighten up nicely...Loving the accuracy, getting used to holding the gun correctly as well...

Did some 50 meter shooting with my Hw30 5.0 today, scope is hawke vantage 4*32, sitting down with the triggerstick as support, pellets was h/n field target trophy, the black 8" target was used first hold 2 mildots over and shot 6 shots, hit a bit low so aimed a bit higher for the rest of the shots, the target is the wrong way in the picture, the 2" targets i shot 3 times each except one that i only shot 2 times cause it's hard to count so long...

I LOVE how old this thread is. Here is 10 jsb 10.3’s @27y — 11 ft lbs (700 fps) via an HW97K (shot while listening to a boring work conf. call — if they only knew). But i got a question: this gun’s power keeps slowly slipping. Maybe 4k pellets and now down to 10 ft lbs. Its still accurate, but at what point do I rebuild? I want to shoot some springer HFT at a club this summer. Should I bring it back to 12? Can I do it by shimming the spring and changing the seal? Never opened up a springer. Dont want to F’ it up.
