2300S vs 2289 breech..
« on: November 26, 2022, 08:39:16 PM »
Hello all, I have a Crosman 2300S and 2289 both great air pistols  :) when loading the 2289 (plastic breech) its a simple process, however when the 2300S lets say its not as smooth. Im assuming that's due to the steel breech? Maybe the J&B paste job would help??

The difficult loading you are encountering with the 2300s has to do with the pellet touching the top of the screw just inside the breech that connects the breech to the air chamber(Part #5).
Some people polish this screw.
Some people put some wax on it.
Me?
When chambering a round I lift the muzzle vertically and the pellet chambers effortlessly.

Hello Frank and thank you for your input :). The screw is under the probe so I don't see how that's possible to be interfering with the movement of the pellet  ??? Its not that big of a deal I just have to give it a little more push to get the pellet into the barrel. I'll experiment with different pellets to see what happens, again thank you for your input  :-*

The 2300S and 2300T have the rearward located 4-48 screw steel breeches, although one is the short breech and the other is the long breech.

In my experience, the plastic breech on the 2240/50/60, 1377/22, 362 guns, even with its limitations, does operate a bit smoother than the steel breeches because of its softer surfaces.

Check for burrs in the port of the barrel - the pellet head may be catching there.  Try feeding the pellet with the barrel pointed up and see what this feels like.

Polishing and/or  careful fitting of the barrel-to-breech diameter can help.

See attached image of a 1322 with polished barrel and the long steel breech with forward located 4-48 screw.  Please ignore the embarrassing amount of dust on the camera lens!   :-[     Note that the breech has additional barrel retention grub screws, the third of which is directly above the TP.

Shot the 2300S today and tried the muzzle down and it did help a bit but still not as smooth loading as the 2289. Again thanks to all that gave suggestions  :-*.

Polishing the transition on the end of the barrel should help, just be careful not to take too much off since that's where the breech O ring seals...

I usually load with the barrel up method, that way I can get the skirt on the tip of the probe before pushing it forward, too easy to get the pellet sideways or backward with barrel down, but I haven't shot a lot in a while...

About a 45 degree angle up works best with mine.
