I have added a Crosman steel breech to my 1377. Put in a flat top piston and valve with a lighter spring where it would dump all the air. It was shooting great and they after shooting it a lot the cocking handle takes an extreme effort to pull the bolt back. Unlike my 2240 with a Crosman breech. Both have the original bolt. The binding doesn't start until I install the breech. Any idea what it could be?
Thanks
How did you get a (one pc) stock bolt into a steel breech?
And, assuming I didnt' miss something in your notes, it sounds like you have a screw length issue with the rear most screw at the top of the breech? If it is too long, it will interfere with the hammer and cocking sequence (so will the bottom screw directly in line with it).
Did you drill and tap the old bolt handle out! If you did you may have swelled the hole in the probe a little! And I 2nd what BDS said! About the screws maybe being to long! Hitting Hammer or spring or both! You will probably have to take apart and check for signs of something being hit! Also check your probe bolt, sometimes they can be just a little Fat! And need to be dressed up a bit!....John ???

I just installed the Crosman steel breech on my 1322 and had to take the stock rear sight screw and cut it off 3 1/2 threads. I checked all that before I installed the barrel.
The rear breech screw from the OEM breech is too long to use with the steel breech. As mudduck stated, take off @3 threads to shorten it up. Don't know why Crosman does not put that in the installation instructions. Now, the screw is snugged into the hammer spring restricting it from moving properly.
The Crosman steel breech is made for the 2240. It said in my instructions to take the gun apart and save the rear breech screw. If you can take your rear breech screw out of your 2240 you will see how long you need to make the screw for your 1377.
Whenever I have purchased a Crosman long steel breech for any 13xx gun it has always come with a new rear 8-32 screw of the proper length.

Mine didn't. Another .15 Crosman saved to give to the CEO

Was it a brand new one in the package? Did you buy it from Crosman?

Yes it was and yes I did.
They get enough customers with these problems calling them... that screw is going to go back in the packaging I would bet.
I can't hold it back any more sorry. Read the title backwards. ;D Something Chief Crazy horse would say.

Sorry I didn't say I installed a long breech from Crosman that included a bolt and separate handle. And that I upgraded the cap screws with SS hex screws. Thanks for the great response to this nubies problem. I will shorten the screws. Now I think back this started after that mod.

It was the rear breech screw. Thanks and stand by for more questions from a newbie. It's fun a addictive with no cure in the near future.

Good to hear it was the screw length. I believe that just about everyone has been on that road myself included more than once :-X

Yep, that is the kind of 'bad' screwing that none of us need, ever.

Yep i bent the hammer spring once.

^^^ Did the same thing and then went so far as to break of the brass bolt handle I had. Too dumb... :-[
Carl
I did the same thing too with my first steel breech.....we all must think alike :D

For sure... it is one of those Crosmanitis things we all suffer from. :D
Actually I'm not sure we suffer from it but rather we enjoy it... :)
