After quite a struggle and with A LOT of help from Jason (nervoustrigger) I finally had my scope set up perfectly. It's a 1377, steel breech with a Bushnell red dot on it. It required adjustable rings the get it shooting straight, but last year I was able to split in half a Ritz cracker sitting sideways on edge consistently at the very short range I shoot. It was perfect for HOSPS.
This year it was spot on again until I lifted it in the case that I thought I had zipped closed.THe gun fell on the floor from about a foot and a half.
Bottom line: It now shoot slightly off, but not consistently in one direction. I believe some screws loosened and they had Lok-tite on them. My question is, if I find a loose screw and tighten it up will the previously installed Lok-tite (a year ago) still hold? I wouldn't think so but with it still stuck to the threads I thought maybe it would still hold well enough. No recoil involved since it's a 1377.
Sorry for the long post.

I'd look somewhere else if I were you. I seriously doubt it's a loose screw, check for leaks, in a 1377 the only screws that can cause a leak and affect accuracy are the breech screws.
Check if the transfere port is leaking this is the weakest link in the 1377.

No chrony here to test that, but I don't think it's leaking. It still holds air for hours. Still seems to shoot strong but I will be testing more tomorrow off a bench.

Did it land on the scope??? If so, the tube may have bent. That happened to me with my AR-15 and it bent the scope tube.
Now I had a $350 paper weight so I did what any red blooded Americans would do when there is nothing left to do. I found the high spot by turning the scope in its loosened mounts, tightened them up again and whacked the front of the scope with a rubber mallet. The bend was reduced considerably so I did it again until it turned perfectly round while being measured with a dial caliper.
A trip to the range and two clicks to the left got me right back on target at 100 yards.
Loosen your scope mounts and turn the scope to see if you got the tube. If so, the rest is up to you :P
-
Yeah, I think I would remove the scope and take the gun back to basic open sights and do some real close range testing (20 to 30 feet). Eliminate the gun or the scope as the problem.
-
I believe it did land on the scope. I was kind of in shock when the case sudden got lighter and herd the thud. The gun is fairly top heavy too.
What's weird is it's not too far off. I just miss a bit high/low or left/right but no consistently in one direction. I'll test further off bench and report back.
-
Ouch Jerry! That hurts just reading it! I sure hope you can dial it all back in. ;)
-
Thanks Bullit. I just got done benching it, and with a few adjustments it's shooting perfectly again. One ragged hole at my only HOSP shooting distance of 8 yards.
Appreciate the help guys.
Edit: Just set up in the indoor blind, gonna test it on HOSPS. :D

I guess you dodged the proverbial bull.... er ... pellet.

He should get the maximum 100 lashes with a wet noodle for dropping it in the first place, not to mention admitting it.

I've learned, and it won't happen again. Making a thread admitting it was punishment enough.
That gun is heavy with steel breech and scope. It didn't fall far but hit hard. I got REALLY lucky.
Not to mention due to a QUALITY original installation. ;D Thank you Lok-tite.

I've never dropped one, knock on wood, but, I've sure come close a couple of times. Sure gets your heart pumpin'.

Yeah it do. I have not dropped one since I was a kid, and back then I did not use scopes.
Now I mostely use Red Dot sights :) .
Though a couple of months ago I came close to dropping one of my 2289g's with a home made strap, one end came undone while it was on my back and I had to reach back in a hurry.
