Got er done and it was an adventure in cheap rifle construction. It is imported by Umarex for Ruger and the same rifle has carried three different Ruger model names. It is a real piece of junk on the inside... Or, finally, " gee, wonder how long it will take to remove two perfectly good boards to recover .25 cents worth of parts"?...
...Now clean the interior bits, a little lube and black tar - and, using all three of my hands plus one black lab to retrieve flying parts, put it back together...
...After 40 shots to reseason the squeaky clean barrel, it shot 1" @ 25 with the occasional flier. Once again good enough for its intended purpose shooting at the top of squirrel trees.
Anyway, thanks to all for the advice and encouragement. Did I mention a beer and cig? Always smoke after s..pring gun tuning.
"Piece of junk". May I assume that yours is like the one I tuned, and says "Made In China" somewhere on the rifle? That usually explains a lot in the way of 'less-than' quality and precision.
I've always assumed that soldiers in the field from other countries "shooting Chinese-made AK-47's", were probably at quite a disadvantage. If their air gun production and QC is any indication, if 'something (usually) comes out of the end of the barrel and goes somewhere when you pull the trigger', the factory inspection guy says, "Passed". (I know there are some good products from China, seemingly more so in the past 10 years or so . Cheap spring-piston guns just don't seem to be one of them). (Admittedly, I'm jaded from such past experiences).
Your sense of humor is more than adequate, and all things considered, I'm thinking you might not have been able to do the job without it. A wise acquaintance once told me, about an unrelated field of endeavor, "Keep that sense of humor of yours nearby. You're going to be needing it"--your comments about the boards and the dog are funny.
So, is that 25 yards or 25 feet? Either is fine considering what you started with--just wondering. I'm 99% sure that I had to resurface the barrel crown on the one I tuned to get the accuracy in the general ballpark. You can't do much about a barrel with a bad bore/rifling, though.
