I have a Slavia 624 in .177 cal that I bought over 35 years ago. I tried shooting it a month ago and it would just barely dent a thin cardboard box. I mentioned it to a guy at work and he told me that the leather seals are probably dried out. He said to break the barrel open and fill the gun with 3 in 1 oil and let it sit upright for awhile and let it soak in. I left it for a month and then took a shot from it in my basement at a cardboard box. Surprised the crap out of me that it went through the box bounced off the floor and hit the wall and bounced off the ceiling somewhere. Probably wasn't a smart thing to do but I really didn't expect it to do anything. Couldn't believe filling it with 3 in 1 oil actually worked, but I wonder for how long it will last. Took it outside to the back yard, filled a 2 litre bottle full of water and set it about 20 yards away. Took a shot at it and it blew a hole right through the other side. Now the kid has a gopher gun to play with and I didn't have to spend any money.
