I think you’re going to have a very difficult time getting a phantom to 800 fps in .22 cal with any reasonable weight of pellet. The most I’ve got was in the mid 700’s using 14 grain crosman.They are good little light weight guns at a bargain price. For 40$ you could get the full power spring and a new piston seal delivered. Your piston is the full power with bleed hole. I prefer to use solder in the hole rather than JB weld . Don’t forget to have a good look at your breech seal.

Hers the parts list you need
Piston seal-B18-04-1A
Spring -B18-00-4D
Breech seal - B20-00-3

And the piston if you think you want to replace it. B18-04-100A

These are the parts for the phantom 1000 CS1K77 /x

Ok. So I tore into my Phantom .22 after reading all the great advice. This is what I have found. My Piston is 5-3/4 inch long and has the bleeder port. I have already use some clear JB
Weld on top and bottom of the bleeder hole.

My Spring is about 9 inches long and I counted 34 coils if I counted properly. I am looking for advice as to how to make this a good tack driver till I can save up enough to buy a good air rifle. I have firearms and allot of .22 powder burners, but have recently enjoyed catching small game with the air rifle. I just wish it was more effective at a further range. Where do I go from here?

When I put it back together, I will have some shims in the spring to try it out for now. But I would prefer to change the spring for the full strength one. I would be happy to get it shooting around the 800 FPS or a little higher if possible.

With the limited budget maybe a used gun out of the for sale section might be better.Just seen a Diana .22 for $250.

Thank you for the heads up. I am still learning how to navigate around the forums and haven’t found the used stuff for sale yet.
