Mike,
Thanks for the compliment on the range. Did I mention it's lighted so I can shoot at night(least wind)?
I have a background in competitive shotgun shooting(mainly sporting clays and skeet) so I had made a lighted 5 stand to practice on in the field behind my house. Since I have gotten back into airguns, I decided to make one for airguns in my back yard too. Lots of stuff on order(more pellets, targets, wind socks and spinners, etc.). Also have access to a 55yd warehouse at work(no wind).
I have a .22 Edgun Lelya, and a .25 FX Wildcat, but right now, I am working on my .22 Crown Continuum(trying different pellets/slugs at different valve, hammer spring, and reg settings), 380mm vs 700mm barrels at different speeds, learning barrel cleaning frequencies, etc. So there's a lot to "wade thru" to learn what affects what as it relates to accuracy in different conditions.
I wasn't really posting any of those targets for inspection, but I did notice spiraling on the some 100yd shots(more at some speed than others) and I suspect spiraling would be the culprit for loose groups at 50 that didn't get that much worse at 100? Yet to be proved tho.
I also noticed that when I shot the 15.89 jsb at an insane 1100fps, they grouped much tighter at 100 yards. Wind moved them easily, but they all ended up hitting close together. 50yard accuracy wasn't that great tho. That being said, these are just preliminary observations.
I'm looking forward to Steve's complete AEAC review(probably Friday?) on the .22 Crown Continuum to learn if there is any commonality help to limit some of the variables I'm juggling and maybe steer me in some helpful directions.
Thanks for your input, Phil
