It's my understanding of the earlier models had a different size compression tube. At what point did the comp tube change size? Is there a benefit from the older version to the latter models in this respect? Seems some say yes and some say no.

How many of you own an HW77 with the Goudy stock? I would love to see your pics of them.

Thanks

I have three older 80s guns with the 25mm tubes. The consensus is the smaller piston guns shoot smoother since the piston is lighter, and easier to push being smaller. I have found this to be true, but slightly so. Not a huge difference. 

They do shoot particularly well with a slightly enlarged transfer port at about 12fpe.

The two piston pic is a side by side of a factory 25mm piston, and the 25mm from my Venom, that had the stroke lengthened by about 12mm.  

The older Goudy stocked guns feel lighter and slimmer than the current models. I love these old guns.

I'm not sure the serial number range for when the 25mm to 26mm change took place. But one quick way to tell a 25mm is look at the underlever catch and loading port opening. The MK1 had a ball bearing underlever catch, and the MK2 had a sliding catch. Both had small loading port openings. 

The MK1 has 25mm internals, and I'm almost sure that all of the MK2 guns did as well. Maybe that helps.

Absolutely helps. So was the transfer port larger from the factory with the 25mm? I may have misread.

The Venom is gorgeous, but there is something about the factory K that I really like, maybe in its simplicity of sleek lines...

That is a beautiful example you have! Nice back drop for the photos too.

I think I have found another itch that may require scratching LOL

No, the 25 and 26 had the same transfer port, 2.9mm. 

And yes, those Goudy stocks are nice and slim and trim. The cheek is a little low for scope use, but otherwise they are wonderful.

I have Beeman import HW77K in .20 that a friend bought for me from an estate sale many years ago... shoots great, and is one of my favorites.

Believe it to be a Mk2 with the barrel latch... the serial number (1145xxx) indicates that it was manufactured in 1985-1991, according to the Weihrauch website.

I assume it is the small cyclinder, but I have yet to have it apart... I suspect the original owner ordered it from Beemans with a "super-tune" back when Doc Beeman was in love with the .20 caliber, but I'm not positive... here is a photo of it.

If I come across a fine example like you guys are showing I'll try to grab it. Always wanted one.

From the UK forums:

Originally, rifles before s/no. 1446049 were all fitted with the 25mm set up.

Chase has a nice example, and keeps them Alabamy bushy tails in full retreat with his.  From what I gather the 25mm is the best shooting of the underleavers.

There's a MK2 .177 in the truck right now, waiting for daylight. Season opened yesterday! ?

So did the od remain the same? Ihave a long 77 that I might as well part with, very seldom gets any shooting and it,s a bute. So sad...

You mean the outside diameter of the compression tube? If so, yes it was always the same size.

@straitflite - Mine is a factory tyrolean model from Beeman (1991) Santa Rosa and is very nice looking with a top grade dark Walnut Wood.

I have a MK1k in .22 that I haven't shot in a few years. I should break it out soon. I'd have to figure out what scope to put on it(No advise needed thanks). Of course, mine Also has the "NOT really a Goudy" Monte Carlo with a raised cheekpiece. Was there ever a true Goudy stock offered from the custom shop (straight comb with a raised cheekpiece)? I've never seen that. In walnut or laminate?

BTW mine is a Hull Cartridge Weihrauch. No different.

Yeah, that Venom has a nice piece of lumber. Nice gun

Glad you asked that question Brian. I was wondering myself if the stocks for the 25mm & 26mm stocks would be interchangeable. I believe Limbshaker has answered that for us.

The HW77 K Mk2 that I picked up at the Arkansas airgun show last year, has part of the receiver stamping slightly receded below the stock. The stock bottom screws show someone has applied serious torque to them -or perhaps from a bad fitting screwdriver?

In any case, I'm hoping that the rear of the stock hasn't spread from over tightening and perhaps mine isn't the only one with partially 'hidden' stamping? Haven't done any sighting in yet...

@limbshaker Saw you post from way back in 2020 regarding a Venom Vantage that you own.  Long stroked HW77k I believe.  I recently acquired a Venom HW77k Verminter.  Serviced it and found the identicle long stroked piston in mine.  A friend of mine contacted Ivan Hancock (one of Venom Arms co-founders), sent him photos of my airgun, and confirmed that Venom indeed made my airgun and that the early Venoms had that very same long stroked internals.  My Venom was made in 1987 and Ivan remembered my gun.  Now, I'm trying to get paperwork with his signature on it to prove the provenance of it.

I have HW77 Tyrolean stock, action is gold plated, stock is kinda ugly beech. Wish it was walnut. Needs re-plating because Flitz polish did damage to the plating.

I sold a Hull Cartridge in .22 with a walnut stock tuned by Russ Best, I'm thinking 8-10 years ago.

Wondering if yours is the one I sold.

Appears to be in good hands if it is.

I wish. But I already stated mine has what many call a Goudy stock but they actually aren't. But you are correct in saying it would be in good hands if I owned it.

Once while visiting a well known enthusiast I got to fondle a sweet full length HW77 Venom. I bought a couple desirable guns but no price was stated for the Venom so I passed on even asking. Maybe I should have but Yikes! $LOL$
