My Gamo R-77Combat pellet gun pistol is jamming any solutions?

Question

The pellets are getting stuck in the barrel

Answer 1

You have to clean it with a brass brush made for the job, it should fix it quick and easy in about 50 strokes to get the lead residue out.

Simple as that, unless it's low on power. In that case the seals need help probably, which isn't hard to do if you understand the mechanism. If not get some advice from the company or a pro to replace the seals and it will be like new.

When you shoot it hold a hand back by the action and see if some air is blowing out. A very little is normal, but a substantial puff is a blown or worn seal problem. If it's not old call the place you bought it and replace it. I think they have a warranty. Bad thing about Gamo is they make you send it to Mexico for warranty work, so it's usually better just to do seals yourself if you can.
