13xx steel breech question. Need several responces PLEASE. S.O.S.

[Relentless Holiday]

You can also just point the barrel down then drop load your wadcutter pellet.

Thnx but that was still turning em sideways....hunting black crayons for it. They hang up pretty badly

[WyoMan]

Just fitted another flathead... this time to a steel Crosman breech (arrived today).
Turn the head to .188" and part-off leaving about 1/4" of threads. You can go less on the threads but some extra length helps fat-fingered folks position the screw. Knocked it out in less than 10 minutes.



If you want one, PM me a mailing address-

I'm having the same problems with my 1322, where do you get the screws? I have two more steel breechs I need to install.

All steel breeches are not created equal.

The Disco breech has scope rails the entire length of the breech.
I like that version since it gives more area for the scope rails to attach.
Just has the rear breech screw hole and a recess in the front as pictured.

P/N 1761-019, cost $25.33 (breech only) direct from Crosman.

in your pic the disco breech has the screw hole in the back of the loading slot not the front . wont work on a 13xx .

I just got 5 breech kits from Crosman 3 2240 kits and 2 1377 kits and they all have the front screw hole. I know that I got some in the past that had the rear screw hole like the one in the pic. But I don't know if I bought it as a kit or not, or what the part number is to order the rear hole Crosman breech if I want the LPA sight on it.

[JeffB1961]

IIRC the rear screwed ones fit the 2300kt and the forward screw version fits the 2400kt ... or vise versa .

[Tack Driver 10]

I have a 2400KT that I ordered from the CS and it has the rear breech screw.

I just drill and tap the tube for the 4-48 screw where needed.

[Rabbit\Squirrel Killer]

I have 4 CS 2400's and yes they have that rear screw hole. I also several guns I put together that have the rear screw hole. I probably bought them off eBay? I am wondering what the Crosman part number would be though.

Quote from BillK:
Where do you want the breech screw to be?  Front or rear location.
The rear location is best for .177 but many/most 13xx air tubes don't have a rear screw location drilled in the tube.
The 22xx tubes have both front & rear location holes drilled & tapped.
AS2250-025... Long steel breech w/rear screw loc.
AS2250-A013..  "        "       "       "/front screw loc.
2300-047... Short steel breech w/rear screw loc.----$27
AS2250-020 is the rear breech plug needed with all steel breeches.

Thanks I added that to my part number document. I had the Benjamin Discovery breech # on it already.

Don Cothran breeches also come with this kind of screw in stainless.

The Magnum Airpower stainless Torx screw won't work on Don Cothran breeches--probably it will if you reduce the screw head's diameter.

Just received my 1300KT... (TO SAY THAT I'M DISAPPOINTED WITH THE WAY PELLETS LOAD INTO THE BREECH WOULD BE AN UNDERSTATEMENT... 90% OF THE TIME THE PELLET EITHER TUMBLES IN SIDEWAYS OR CATCHES ON THE NOSE OF THE PELLET AND JAMS). Doesn't seem to matter whether domed, hollow point, or wadcutters... nothing loads worth a darn!!!  I couldn't comfortably take this anywhere without carrying a dowel rod to dislodge jammed pellets...

I sure as *(&^ don't want to void the warranty by melting crayons into the breech... not that it wouldn't work.  Do you suppose Crosman would suggest this as a solution to correct the issue... maybe they ought to melt crayons into the breech before they ship them???

This appears to be a faulty design on Crosmans part... I would have thought that an issue like this would have been corrected long ago (seeing how so many people seem to have the same issue).

I have a 1377 Classic (bone-stock)... and while not the easiest to load, it doesn't have near the issue that the 1300KT w/steel breech does.

This is clearly an unacceptable issue that needs to go back to the drawing board and corrected... this model should be discontinued until corrected, and a recall should be in order.

From my experience, I would not (could not) recommend the 1300KT in .177 caliber to anyone if this is the standard condition for this model.

Try the melted wax.  It won't hurt anything nor do I believe it would void the warranty.  You really haven't modified the gun.  Besides, the melted wax would not be too hard to remove.

[Moke]

I load the pellet on to, or in front of, the breech screw, and then tap it in with my finger. No hangup, no binding.
I plan on using the black crayon mod when I mount an upgraded breech.

And I should shutup now, as I've only dealt with the 1322 breech, not a 1377.

You think the Crosman breech bind is bad? Try a Beeman Chief, and its air passage within the breech, and watch the pellets spiral down range. That air passage distorts the pellets if you're not really careful in loading them, and causes misflights.

[anti-squirrel]

I have a pile of various Crosman Lego and have always tilted the gun down just out of habit.  I shoot wayyyy too many wadcutters, especially the RWS Meisterkugeln wadcutters.  Saying Crosman need to recall and discontinue until fixed is a bit over the top, IMO.

I prefer the rear breech mount, but on one of my various Lego guns I used JB Weld and just filled the hole up front.  Decidedly more permanent than wax but the pellet-tipping problem certainly went away!

[moorepower]

Melting wax is not going to void your warranty. The only way to perfect would be to sell two breaches. I have been thinking about turning down the bolt and gluing in a bit of brass tubing that has been split for a loading ramp. Using the rear screw breach is the best solution, as all it takes is drilling and tapping the rear hole. Making two different breaches would add a quite a bit to the price of the breaches.

[rocks]

yes 1377 and 2240 same breech as i notice this myself as the probe was taped for a different bolt they sent me another probe
