Well looks like the seals are shot. Won't really hold any are when ya try to pump it. In the bright said a rebuild kit is less than $20

Love the comb rise ...they were onto something with the Monte Carlo stock of my Weatherby .

Well went and got her resealed. $14 and about 30min real easy job ! The insides where pretty gunked up but other than that eveything looked just fine. Regardless cleaned it up put in the new seals and a little pelgun oil and she's holding pressure and slinging pellets!

Oughta work well on the yard vermin.

That does not sound like a very good gun to me. The cheap bb guns we had in the 80s would go through a tin roof with no problem. We had to power down to shoot inside the barns. A starling would be penetrated with just 3-4 pumps.

Yep 8 pumps and the pellet will go through a rabbit at 45 yards and I could hear the pellet hit the barn on the other side with my 5mm Sheridan.

It would not shoot through squirrels . Always stopped just under the skin on the opposite side. But with the steroid kit I had put in and the heavier pellets that are offered it will easily shoot through them now.

I have this old Sheridan Blue Streak in a 20 cal.(5mm).

Love my Sheridan silver streak 5mm

Way cool.

remember to oil it every 6 months or 1000 pellets which ever comes first and store it with one pump on it to keep the seals good.

they don't seem to dry out and shrink with 1 pump on them like when left with no air under pressure

Out 6yd in low light last night in the car port. About 10 pellets in this group 8 pumps each

Like how you got it back to shooting good Wolfdog. Nice plinker to have around.
