HW/Weihrauch HW77 .22 energy level

[extradrygin2001]

So I got myself a HW77 .22 a couple of weeks back. Just wondering about power levels and what is to be expected. All the YouTube people are telling me 20ftlbs is the norm. However I’m getting 14 ftlbs, accuracyis outstanding. Better than my “tuned TX200”. So I don’t really care about power but I am curious as to what actual numbers are to non-YouTube people.

13.5 to 15.5 is they”sweet spot” from my experience

 

[DualMagMike]

20fpe is above factory norm even for an R1 which is normally around 18!!!

Are you sure you're not mixing up 20 ftlbs with 20 joules? Never seen a 20 ftlb HW77. In 22 they're 14.5-16 lb Depending on pellet and assembly lube dieseling. They can be tweaked for a little more but no where 20 ftlbs.

Unlikely that the HW77 will go to 20 FPE without detonation of lube. Keep it under 16 FPE for a manageable experience. As was stated above 13-14 is much better for accuracy and feel. Don’t get too hung up on power or speed - took me a while to understand that when I first got into the hobby.

Here is an HW97 22cal I just tuned last month.

Tuning - New HW97 22cal Tune

After waiting several months for AOA to get in an HW97 in Blue Laminate in 22cal, it finally arrived. I have only sighted it in at 18 yards last night as I just finished up the tune. Below is a pic and some FYI info if anyone is interested. The tune is a standard Maccari tune kit with Vortek...

All of the responses are exactly what is was expecting to hear thank you all for responding. I never expected the rifle to be above 16ftlbs and the 14 that mine is making is exactly what I thought was to be expected.

What an excellent creation the HW77 is and I swear after 500 pellets through it and me doing my part, I will put it up to my FX M3 .22 at 30 yards any day of the week. This rifle totally rekindled my appreciation of a quality spring rifle, no tune required!!!

Those are big numbers! But yes, unturned, more like 14-15 foot pounds = 20 Joules

Just cronnied my HW77 long in .22 , Monsters 15.89 @ 620 FPS = 13.6 FPE, thinking to tune it to 10. 5 will make a good shooter .

That's about right.

Contrary to common knowledge you can believe everything you see on the internet, there has never been a stock HW77 that produced 20 foot pounds.

Keeping pellet speed under 850 fps is the trick to a great shooting gun period

 

[Toxylon]

The 77 peaks at around 18 fpe, if accuracy is to be retained.

I have the Vortek PG4 kit installed in my HW77. Shoots the Baracuda Match 10.65 452's right around 850 fps. Very nice platform and easy to cock. Tried the 13 grain pellets and it did not like them at all.

Wow! That's honking for a 177 HW77. Thats 17 fpe which is pretty stout for a 22 HW77. All my springers lose lots of power with Barracuda Match's. What's that thing do with 8.44? Supersonic?

My 97 with a Vortek kit made about 15 and a 22 HW97 I did for a friend made about 16 with a Vortek kit. I cut mine down to 14 fpe because I wanted accuracy over power.

 

[beerthief]

would love to get my .22 77 tuned down to 10/11 , being a long barrel , i think that would be the best FPE .
Any arguments against this ?

It's unnecessary to cut the power that low. If you wanted it that low, find a 25mm piston and compression tube.

There's no reason that a 22 97/77 can't be supremely accurate at 14 to maybe 15 fpe. The soft spot in accuracy will be the shooter or barrel.

I had a 97 laminated and it was getting roughly 14.5-15 with all stock parts. My new diana 34 is actually shooting that exact power also.

 

[Wildcatter]

I have a 77K that has had the full blessing from John Thomas, full power and accuracy was the target for this tune. I am getting single digit ES, and averaging 725.9fps with the H&NFTT @14.66 grains for 17.2 fpe. This is for small game up to racoon and if you can get close enough for head shots, coyote and ground hogs.

I also have a 54 Diana that I tuned myself with a custom SHO 4pg spring kit from Vortek. That rifle is shooting 18 grain AA Heavy Field Diablos at 735 average fps an it is giving me 22 fpe which sounds like a lot. But to be honest out to 40 yards, as far as I use these rifles hunting. I really don't see that big a difference in their ability to take small game.

I dropped to the lighter lighter FTT in the 77K and for flat shooting out to 40 yards, both guns show very little defiance in their aim dead on ability. I have not taken anything bigger than a possum with them to this point. Im sure a coyote or ground hog head shot at 35 or 40 yards would be more positive with the heavier pellet in the Diana, but would not hesitate to take the same shot with the 77.
