Well I've been quite happy with my Crosman F4 177cal but yesterday the wife sent me up to the attic to look for some of our old photo albums. in my search for them I came across my old... And i do mean old pellet rifles a Sheridan Blue Streak, and suddenly I was back to being that 17yr old that bought the gun home from K-Mart. I know at the time this pump pellet gun was the cats a&& when it came to accuracy & power. So heres my question, I know there no longer made and I'm not a smith so can seals and parts be replaced? If so can anyone tell me where I'd find them? Or should I just leave well enough alone and put it in our summer rummage sale. Idon't want to spend a arm and a leg trying to restore it, but if I can do it for less than 100.00 I would. I know it used 20cal pellets I don't have any (maybe I do but the attic is full of things) are the current 20cal pellets okay to use in the old girl?
