Having been pleased with my .22 HW100, I just bought a second one in .177. Both are the "K", or carbine versions with laminate stock. I prefer the balance of the shorter carbine, and the laminate stock has an adjustable comb, which I find very desirable. My reason for posting, I have read numerous reviews of the the HW100 in .177, and they consistently report it being delivered shooting too hot, as high as 1,100 fps with a 10 grain pellet. At that speed, I would expect unacceptable accuracy, especially at 40-50 yards, or more. Well, it's good news/bad news with the carbine. The .22 shoots slower than many folks would want, mine is now set at around 880 fps, but with the 16 grain pellet, and a good tune with the 18 is around 830 in my rifle. But, the .177 was delivered shooting slightly over 900 fps with pellets in the 10 grain range, depending on the specific pellet. A slight HST adjustment got it around 880, I figured no need to mess with the reg. So, the carbine seems especially well suited to the .177. My guess, they use the same reg set point in both full length rifle and carbine, and the difference is the barrel length. I think the Weihrauch site indicates an approximate 7 inch difference in barrel length, which is a lot. But, the charts on the Weihrauch site practically defy human understanding, so I'm not sure of the exact difference, but it's substantial. With its short cylinder, shot count isn't great, I think I'm getting 45-50 in the .77, which is adequate for my needs.

Great guns , I’ve recently acquired an Hw100s in .22 . It was an older model, I ended up installing a 410mm barrel and and upgraded cylinder with fill probe. Sure wish Weihrauch would release a .25 cal .i like to reduce my hammer preload until the hammer free fight to hit the valve stem.this usually required lowering the reg to 85-90 bar , they end up super consistent and way better efficiency.

Yes, I'm sure I could play with the reg and get a more efficient tune. But, I don't think the consistency could be improved, and the shot count is fine, so if it ain't broke......

I have the non carbine version in .177. It did come from AoA shooting way too hot. I don’t remember exactly, but 10.34 were over 1000fps. Reg was at 120bar or so. I turned it down to 105 and adjusted the hammer spring back so it was shooting the 10.34 at 885fps. I get 6 full mags, 84 shots, on a single fill. Accuracy is superb. Mine is the thumbhole stock. I would consider another, one but a carbine with a sporter stock.

Sounds like we are at about the same place with our tune. I don't have a reg tester, so I left it alone, since it was shooting about where I wanted as received. The full length version has a significant advantage in shot count, if it matters.

Ed, you wouldn’t happen to have pics of the groups you’ve shot with the .177 would you? To me it’s a toss up between the carbine and sporter but I’m leaning carbine because I know it’s gonna end up in the woods and the barrel leaned up against a tree while hunting.

No, and pictures of groups is, IMO, worthless. I think 90% of the one-hole groups posted fall in one of two categories; they are either a total fraud, or, the exceptional group that is far from the average. I can tell you I have shot 50 yard groups that probably average .7". I know, doesn't sound impressive, but remember two things: fIrst, that is an honest report; and second, usually 4 out of 5 shots are half inch, with a flyer that expands it.
I'm very pleased with both of my HW100 carbines
