As soon as I typed the title I thought, this is probably a small enough group to do a Zoom conference! With everyone playing with FX and other rifles with a mother lode of adjustments, the a HW100 group may be a dying breed. But frankly, I don't think there is rifle in its price range that offers comparable quality of material and craftsmanship; it's just a good ol' rifle. I just got a carbine version in .22 with adjustable laminate stock. With the JSB 18, I'm maxing out at around 860 fps with the current reg setting. Given the short cylinder in the carbine, shot count is modest at best, so I'm not going to immediately turn up the reg. I'm getting 900 with the 16, so obviously I can tune that one to its sweet spot with hammer spring adjustment, which seems to be around 880 in all my rifles. I don't currently have a .22 set up for the 16 grain pellet, so I think that will be my first tuning attempt, rather than rob any more air for the 18. Finally my question, have any of you HW100 owners used the 16 by preference? Just wondering what the general experience has been.
Question for you Weihrauch HW100 fans

It’s funny how when you start looking at something, it starts appearing everywhere. I’m looking at the HW100 In .177 with the synthetic stock to get the longer air tube. If it is as accurate as what I hear, I’m going to get one of the Aeron aluminum chassis stocks to put it in and begin shooting Hunter class. They look really well made for sure.

I can't be of too much help both mine are ,177 one stock tuned for 8.44 and the other with a chokeless bsa bbl tuned for 15,4 slugs and 13,43 redesigned. The HW 100 is a great rifle. It doesn't waste a ton of air after you have it tuned I generally go for as low a reg pressure as I can and still be able to get 30 fps over with hammer adjust

I have the same rifle. I get 18 shots all in a range of 787-794 between 200 bar and 100 bar. Hunter Spitz 16gr. I've done no tuning.

I shot the rifle today, with both 16 and 18, with the hammer spring giving about 880 with the 16 and 840 with the 18. Contrary to my expectation, the 18 shot better, and very good in fact. So, since I'm a 50 yard-and-under shooter, think I'll leave the reg as is. I ended up with the HST just slightly higher than delivered. I continue to be impressed with the build quality of the rifle. The only design issue I have so far, the breech opening is too small for most any pull through, such as the patch worm. I can probably use it without the button, and a slightly larger patch to offset the smaller diameter. But the barrel is easily removed, and without the silencer, it is a breeze to clean when off the rifle.

Personally I haven't bothered with the 16gr JSBs in years. They always come in from shipping with the skirts all bent up, and they never shot better than the 18gr. Maybe the same, but never better. The 18gr have thicker skirts and never seem to get bent up especially when I'm hunting and have them rattling around in a pellet pouch. I actually prefer the Air Arms variety myself they always seemed more consistent. Plus places are seldom out of stock of the little 250 round tins of the Air Arms when JSB Heavy are sold out in the big tins. And finally, PCPs tend to be more efficient with heavier pellets.
The 18gr has a better ballistic coefficient than the 16gr on paper too, so they should fly flatter which may offset a small velocity difference between the two. I haven't found the 18gr to "act" heavier than the 16gr in practical use so there must be something to it as far as my peabrain can tell.
But this is just my experience over a few different guns. Use what your guns shoots best or what is best for you. But I certainly wouldn't sweat 20fps on anything either way if it's shooting them well.
If you need a reg tester you can borrow mine so you aint gotta buy one. Just let me know and I'll mail it to you long as you'll send her back home.
Have fun with your new gun!

Love my HW100s - both are full length FAC rifles! My .22 shoots JSB 15.89 domes and Hades at about 950 fps and is getting an easy 2 magazines per fill. The JSB 18s shoot well but I have several rifles that prefer the 15s so that is what I keep in stock.

Yes, you have more air and more velocity in the full length version, but I knew that going in. Although velocity is relatively low with the 18, around 840, it shoots it better than the 16, so I'll give it what it likes. Got the trigger adjusted to my liking, and the rifle is shooting very well. I don't think there is a better value in overall build quality. It's not built to satisfy the endless tinkerer, there are rifles of lesser quality for that market. But if you want to just load and shoot, for a long time, without maintenance problems, it's a great rifle. As Mr. Monk would say, I may be wrong, but I don't think so.

I have the HW100 T FSB in .20 and a HW100BP in .22, I have the .20 shooting JSB 13.73's at 810fps I get about 40 good shots, got the reg set at 90 bar and the hammer at stock setting, I might dial the hammer back some, somewhere around 750 fps would be nice, that will give at least another magazine's worth of shots for me, it's a tack driver.
the HW100BP .22 was shooting Hot when I got it, 1003 fps with JSB 18's, I reset the reg to 90 Bar and dialed the Hammer spring back to where I'm getting JSB 18's at 780 fps, I get 42 shots at full power and they are extremely accurate, I tried the 13's and the 15's, it didn't like them, it shot CPHP's better..... but it loves the JSB 18's

Interesting, that's several of us that all seem to have the best results with the 18 gr pellet. I think Weihrauch makes their own barrels, wonder what pellet they use for testing and development? I think their brand of pellet is made by H&N, might be worth trying.

Mine is a .177 HW100 carbine with a thumbhole stock and 41cm barrel. It had the small 100cc capacity cylinder which only provides 3 magazines and 42 shots. I sold that heavy steel low capacity cylinder which is my only complaint about HW100's. The tanks are super heavy for their air capacity. I replaced the factory tank with an A&M aluminum air tank which fiills the gap between the carbine stock and the barrel moderator perfectly. It is the rifle length tank which is 33cm long and holds 180cc of air vs. the 100cc of the factory cylinder. The A&M cylinder weighs over a pound less than the steel factory cylinder while providing 70 shots. The reg pressure on mine has been increased to 140 bar and the hammer spring tension adjusted upwards to match. It fires CP 10.35's at 910 fps and JSB 8.44 exacts at 980 fps. At 25 yards benched it's one ragged cloverleaf 5 shot groups.. At 50 yards it's 1/2 to 3/4 inch 5 shot groups on a normal day. None of the newer designed Daystates, FX's, etc. are built any better or have any performance advantages over the tried and true HW100. It exudes quality. The only brand of PCP I've found that gives me the same feeling of quality is the Taipan Veteran. Both are great out of the box and built like a tank. No fiddling necessary for someone who just wants reliability and accuracy out of the box.
For the past two years I have wanted to add an HW100 BP to my arsenal. I do not want the HW100K carbine model with a 100cc tank. I want the full sized HW100BP with the 41cm barrel and 83cm overall length. Both AofA and Krale carry this model but only with the rifle length 61cm rifle barrel that adds 8" and makes the bullpup 40" long. It is goofy looking and a total mismatch of components. It looks strange and defeats the purpose of a bullpup to be compact. I'm sure they would sell quite a few more if they just carried the HW100BP as shown by all the Youtube reviewers on both sides of the Atlantic. Has anyone seen one in the full size HW100 BP for sale anywhere without the fishing pole length barrel?

I notice the breech seal is in the action block behind the barrel. Is it in a separate inlet piece? Just wondering how it is replaced, since there is no room to work in the breech opening. Do you take the front modular piece of the action off to access the breech O ring?
