Which pellets are you using in the 1377? Restoring accuracy may be as simple as changing pellets.

I have a 1963 vintage Sheridan Bluestreak that I've owned since I found it underwater in a ditch when I was 12 years old, in 1972. I sent it to MAC 1 for a rebuild and their "steroid" treatment about 15 years ago, and Timmy Mac told me "this POS ain't worth rebuilding". Then I told him the story, and he quickly changed to "anything I can do to get this old girl shooting again...".

Well, the thing wouldn't shoot all that well when he returned it. I figured the barrel was shot. I called Tim and asked him what he thought. He told me to switch from the American made "Sheridan" (now made by Crossman) pellets to the Czech made JSB's, which are a bit larger in diameter. That did the trick. The rifle will now, from a rest, with the original Williams receiver sight, shoot all shots into one ragged dime sized hole at 25 yards. With the old pellets, it shot maybe 3" or larger "groups". All I did was change pellets.

H&N, among others, lists several different diameters for their .177 and .22 caliber pellets. When you talk to the Airguns of Arizona folks, ask them about that. They might be able to recommend something that will get that 1377 shooting well again.
