I have an old Gamo S1K that's been living in my closet for a few years now. It seemed to be accurate, but man it was sure jumpy and twangy. Plus it tore up the backstop something terrible. So it was banished to the closet.Well, lately I've been thinking about a nice easy shooting .177 breakbarrel in the 600 to 700 fps range for backyard plinking. Money's tight right now so it would have to be cheap, uh, inexpensive. Then I remembered to old Gamo in the closet. I tore it down and found that it had a spacer about 1-1/2" long. I removed it and replaced it with a single washer. Wow, what a difference in feel! Still a bit of jumpiness so I took her down again and lightened the tophat. Turned it into a panama hat! Got it back together and mounted a BSA 4x32AO scope. It shoots real nice. I finally chronied it tonight and found it's doing around 560 fps so I think I'll add a few more washers. Got a Charlie-da-Tuna trigger coming for it too. Looks like I'll have a Bubba R7 soon!
800fps with or without the factory spacer?
Gene, do you put a longer top hat on the spring? That is, does it require something to space it up if it is too short? (Sort of like the spacer that JM supplies with his Arctic Kit for the 124, the spring being zero preload and shorter than factory.) A soft shooting S1K would be something I could like.
