When I received my HW95L .22 from AoA they included a readout that stated the rifle test showed an average of 557 FPS using JSB Jumbo pellets. I just got a Caldwell Chronograph and using JSB Jumbo 18.13 gr pellets I got a 4 shot average of 617 FPS. Nothing has been done to the 95 except shoot about 3K pellets through the rifle. Does this seem normal or was one of the chronographs wrong? The Caldwell Ballistic Precision Chronograph was easy to setup and use and the iPad/iPhone APP provided an Excel doc for review/email. Thanks
 
Sounds about right. The velocity rating buy the manufacturer all depends on their altitude. According to Google Mellrichstadt Germany is 890 ft above sea level. That's about 12-15 fps loss so that would put yours are 600 fps (with that pellet) at their factory. Two possibilities. Either your still gaining velocity due to burning lube (after 3K shots I doubt it) or count your blessings. Your 95 is on steroids. Manufacturer velocity figures are usually when shooting light pellets. In some cases alloy pellets.
 
Deerstalker,

14.5 to 16 fpe is the norm. I would encourage you to try H&N Field Target Trophy pellets (14.66 grains). I have found .22 bores in the Hw95 to be a little over sized, yours however may or may not be. I find H&N's to shoot best in most of my German springs. I would try the pellet I mentioned in the 5.53 - 5.55 head size. Chances are you could purchase one tin of FTT's and use a pellet gauge (if you or a friend have one) to sort out different head sizes to determine best pellet for said rifle. Personal I think the 18 grain pellet is a bit much for the platform, just my 2cents. My last .22 hw95 shot the 14.66 H&N's at 700 fps, @ 15.9 fpe, little flater shooting than the 18's.

This may or may not be what your looking for but gives you one more option to try. Enjoy the pursuit.

Cheers
 
You got JSB 18grainers going 617 FPS....NICE. What's your group? I don't trust all these satellite gadgets,downloads/apps. Hardcopy!,Hardcopy! Hardcopy!,take that to the bank and shove it in their face....I mean politely present the facts ???? NOW ,,Back to what matters,,What are the groups you are getting with those JSB 18grainers ? Have you tried other 18grainers like AA or FX. I hope to purchase a 22cal R9 from "Flying Dragons Air Rifles". as soon as they become available again. So I'm soaking up what I can. Already have the scope and rings and a level to butte. I'm getting serious now,lol
 
First test of H&N FTT 14.66 gr through Caldwell chrono had 10 shot average of 688.7 FPS for my HW95L .22. This really surprised me as I thought that the 95 would shoot much slower. Very accurate at 25 yards and such a joy to shoot. Caldwell Ballistic Precision chronograph worked perfectly with no errors on a cloudy day. 10 shot deviation was 5.5 FPS per the iPad excel data using the Caldwell APP.

Yep, my stock HW 95 gets about 680 fps for pellets in the 14.5 grain category. Around 15.4 foot pounds. 

If you want velocity, go with the H&N FTT Green 9.56 grain. Stock the HW95 shoots those at 850 fps / 15.5 foot pounds. It makes sense because the pellet is in the .177 weight range. At closer ranges it'll shoot flatter than the heavier lead pellets. At 10 yards the lead pellets, although still slower, start edging it out for retained kinetic energy. So if you want more punch at longer range, the lead pellets may be better. 

The hybrid plastic/alloy H&N Prometheus 9.0 grain gives you a skosh more muzzle velocity/energy: 883 fps / 15.6 foot pounds. But it has accuracy problems and more downrange energy loss than the FTT Green.

According to my amateur testing, the JSBs have slightly lower initial velocity and energy, but seem to retain it better down range. For example, the JSB 14.35 grain Express loses only 4% of its kinetic energy at 10 yards, compared to 10% for the H&N FTT lead pellet. The JSB 15.89 grain Jumbo loses even less, around 2%. It's a total mystery. Maybe JSB coats them with teflon or there's an aerodynamic boat-tail effect. JSB pellet skirts seem to be more feathered at the edge than the H&Ns. I'm just grasping at straws here.
 
With my .22 HW95L and in the HW80K .22 there is quite an increase in .22 velocity. My HW95L .22 shows similar ballistics to the AOA readouts usually below 700 since the HW80K does 734fps with HN FTTS.

I learned not to take more than a glance at the AOA readouts on their chronographed rifles.

However, an HW44 .22 I have does 732fps with the same pellets!

The R9 is a great rifle in any caliber, but if the chronograph becomes an instrument to use then just see what happens when you just get an HW80 in any caliber of your choice and compare it to the HW95L.
 
Each Weihrauch design hits a sweet spot.

I recently put a Vortek PG3 in my HW95. It gets about 720fps with the 14.66 H&N FTTs, putting it close to the stock HW80. But recoil is right at the comfort limit. Just taking the mass of the scope off increases felt recoil above my comfort zone. I have never shot an HW80 but I bet it's nicer to shoot at the higher power levels.

At one point I was eyeing a new HW90, but finally ended up buying an HW100 K sporter. Even that was a little too heavy for my tastes, so I bought a titanium cylinder. That dropped the weight below 8 pounds. Now I'm a happy camper. 

But do we really need more power in a classic springer? Even a stock HW95 puts holes through soft 3/4" plywood. It'll perforate a chipmunk or rabbit.

It's interesting that Weihrauch doesn't make under-barrel guns with the HW80 or HW90 powerplants. But it makes sense, they would probably be a bit on the heavy side, without adding accuracy. So the HW80 and HW90 end up as primarily hunting rifles. They are engineered for high power levels with relatively low weight. The HW90 is about the limit for power/weight ratio comfort.

Still, I would love to see an HW90 under barrel.

The HW95 powerplant seems to be the most universal, with the most engineering development, being used in the HW95, HW77, HW97 and HW98. That tells you it's right at the sweet spot.
