Question about Ruger Air Hawk Barrel Cocker

What I know about airguns wouldn't fill an empty CB Cap case. A friend asked me to help him sight in his Ruger Air Hawk, it had a Winchester Airgun scope with parrallax adjustment. At 20 yards we were getting 6 inch groups. I thought there might be a problem with the scope so we took it off and at 20 yards and factory sights we were getting 5 inch groups. We were using Beeman high velocity pellets and I did notice that about half the time there was a sonic crack and half not. Any ideas about a solution?

.177 - try heavier pellets

If you're getting over 950 fps or so then you're pushing the speed of sound - and that does nasty things to the accuracy. Heavier pellets will slow it down a bit. ALSO, pellet guns tend to be very picky as to which pellet they like - or don't like. Drop by http://www.pyramidair.com and pick up 4 tins of various pellets, or more. Try different brands - and make sure you've got a clean barrel. At Pyramid, every fourth tin is free, always the cheapest tin of course.

This is a spring-air gun (uses a spring to compress the air for each individual shot, i.e. no resevoir). So, it sounds to me as though you might have a problem with the seal(s) leaking air OR the gun has been fired without a pellet which MIGHT have damaged the valve (which meters air into the chamber to push the pellet). I think either would give inconsistent velocities, change the vibration of the firearm and thus give larger groups. Also, it may be that the seals simply require lubrication/oiling which could also cause inconsistent sealing and thus inconsistent air pressure, but I don't have the manual to check that.
Just as with any other projectile shooter, some projectiles work better in the specific system than others.

If it is brand new it may need broken in
I know on the Chinese copies of the RWS guns they say to run 200 pellets through them before even trying to sight the scope in. I've got one of them, haven't had enough chance to play with it to see.
Yes, the mechanisms work better/more consistently

after "breaking in", i.e. wearing the burrs off the moving parts.
