Hey Guys and Gals,

I just acquired a Crosman 2300T and the person I got it from, one of his friends hacked the barrel off(what a shame), so I've been searching online to see about getting a muzzle crown facing tool and 11 degree chamfer tool to redo the barrel but can't find any Canadian sites to buy them. Does anyone have any idea where I can purchase these tools?, I would prefer to get these tools so in the future if I damage my crown I can fix it myself. Any help is appreciated.

Thanks, Sheldon

If you want to try the cheap way, look for a counter sink or a counter bore of your desired angle. Try to avoid power tools for this and keeping it parallel will be a chore, little cuts at a time. Then check it with a Q-tip , if it hooks the cotton on exit then repeat the process. I only ever did this once and I used a lathe, good luck

I had many good success with just a brass bolt and valve lapping compound.

I took crowns like this, and made them perfect.

Did a Cooey after I cut down the barrel. It shot well, but the flash burns were to one side. So redid it.

Thanks for the helpful advise, I will definitely try these methods until I can get my hands on the proper tools.

youtube is your friend here there are many videos to watch before doing the first one.I used a golf tee wrapped with tape to match the bore size and used valve grinding compound and used the pressure of my thumb by hand until it passes q tip test.good luck go slow check it often regardless of what method you choose.

You would have to be very careful not to damage the bore using this method . it sounds like it may be better suited to polishing the lead into the breach .
