Break Barrel My first Weihrauch; HW 77 circa 1987

[Awl In]

I couldn't be more thrilled to find this listed in my local craigslist "for sale" pages. I had to snap it up because I've always wanted one. Its a Hull Cartridge import to the UK, and the seller inherited it from his uncle. Shoots fantastic; best trigger ever.

What a lucky find. I need to redo all my Craigslist searches. All I ever found so are are rusty Red Ryders, but you never know.

I paid $225 for this. Did I do ok?

 

[PapaT]

Yes, I'd say so.

A little love and TLC, and you"ll have a real jewel. If you can, shoot it by a chronograph before you do anything to it and then again after you get into her internals and get it all cleaned up with the proper lubricants. Thinking of doing a tuning as well? Orv.

I did run a string, and it is pretty consistent around 11fps, from 8gr to ~10gr. Its the UK tune from back in the day.

I have stripped and refinished the stock, and I will thoroughly clean and polish (where appropriate) the exterior and internals. I have the Vortek delrin glide parts coming, including the 25mm piston seal. I do need more power out of a .22 than the UK tune delivers.

I am very pleased with this rifle. It is really an heirloom piece for me, and I will pass it to my grandson.
The stock needs to cure for a week or so, before I condition it, wax and reassemble. This will give me time to complete the rest of the project!

Great news! I finished the stock,and rebuilt the rifle with a vortek delphin HO. I got it back together today; ready to break in the new seal, which was very tight in the install.

And the chrono data . . .. I really expected more power, but thats ok. Shoots great, cocks smooth (more on that), and it was fun watching the SD settle in a bit.

I set up at 20 yards, with the open sights, and started my session. First 50 shots with CPHP 14.3:

Max 679.8
Min 581.4 (one weird shot skewed this string; made a funny sound)
Spread 98.4
SD 15.1
FPE 13.8

Second string of 50:

Max 675.9
Min 629.9
Spread 45.9
SD 8.5
FPE 14.0

Third string of THIRTEEN (13):

Max 665.7
Min 634.5
Spread 31.2
SD 8.1
FPE 13.6

I have read that the vortek 25mm piston seals are tight, and will loosen up with break in. I understand that velocity should increase, and if it doesn't, the seal would need to be mechanically narrowed. Having NO experience with springers, I can only attempt to educate myself by reading what others have posted.

Now, why a 13 shot string? Isn't the number 13 unlucky? Why yes, it is. Not only did I break the cocking lever, as cautioned by TinBum Tuning online, I also buggered the stock a bit inside the lever groove.

I should have known. The lever didn't quite close correctly, I assumed the new breach seal had to seat, and that it would settle in with a bit of use. But no, it broke.

It looks the the delrin sheath may obstruct the lever from going in properly? Any ideas?

I will now be ordering a new cocking lever arm, and probably the rivet/stud as well, so I am sure I will have hat in hand with some advise on that repair. I would also appreciate any input as to the FPE numbers my first few shots generated. I am all ears!

 

[Awl In]

I think I am going to have to trim the delrin spring guide by perhaps .5" so that the cocking arm fits?

1. does this make sense?
2. is it somehow installed improperly?
3. anyone else have this issue?
4. am i out to lunch?

Any insight is helpful; thank you.

Sorry this happened to you after 113 shots. I can't offer much advice, but I'm interested to find out if there is a happy ending.
