Please help me understand this...

Thank you!
That is a better solution to having to keep using my estimated hand strength!

I shot it this morning again and have it under control better than my 57 which is always doing something to distract me and screw up the shot.

It is as if I just bought a 97K-T brand new; and now I am shooting a LOT of .20 pellets!

Now that I realize how easily the underlever can affect barrel harmonics and how important the underlever's affects are for barrel harmonics, I'm going to look into refining the cocking lever adjustment. I didn't even know that the cocking lever could be adjusted on Hatsan Dominators. Unfortunately, it appears that its going to be a trial and error process which means I may never really get optimal performance (whatever that might be).

I've had underlevers before and now.

The "now" underlevers are HW57, 97 and I had an Eclipse .25 with low velocity but high power when it hit.

Anyway, the 57 is very "loose jointed" and this appears to be a design defect of using the lightest parts to make it.  The looseness doesn't affect performance.
The 97 is a workhorse heavy underlever that I hate firing because of its size and weight and Thumbhole stock. I hate it.

The lever system on the 97 is supremely solid but the gun always loosens up and needs re-tightening. Furthermore, the 97 is supposed to be more accurate than an R1 or HW80 and to me it is not.  I think the underlever system in general is subject to more moving parts that just loosen in time.

"the gun always loosens up and needs re-tightening"
What specifically "loosens up and needs re-tightening" other than the stock which was already mentioned?

"the 97 is supposed to be more accurate than an R1 or HW80 and to me it is not"
Hummmm.....when I owned a couple .177 R9s and a .177 HW77k I found it a bit easier to shoot the "77" accurately due to the added weight vs the R9 break barrels and I never had "loosening issues" that affected the accuracy.

As far as "more moving parts that just loosen" goes, the only cocking linkage issue that would affect the accuracy would be a compressed/set breech seal behind the loading port that might allow occasional "blow-by". I shot my "77k" for over 20 years (10s of thousands of shots) and only replaced one breech seal during that time. One curious thing I found with the HW77 was the fact that the front stock mounting bracket was a "loose fit to the receiver" until the stock was mounted then it was solid. Here is a pic of my HW77k loading port..........

As mentioned, as long as the breech seal in the sliding compression tube is sealing well, any "looseness" is irrelevant.

During the 2010 Field Target National match where the hunter class was first included the class was a combined PCP/Piston class and out of 17 hunter class entries only 5 were shooting piston guns. Still, using my home tuned HW77k I took 4th place in "hunter" so it does seem that my particular "77" was pretty accurate during the two day match...........


Anywhoo.......due to the extra weight and added 'arm waving" required to "cock and load" vs my break barrel R9s I only took the "77" on a few squirrel hunting trips. I even left the HW77k home for regular field target matches preferring the "easier to cock and load" R9. A couple years after moving from West Virginia to North Carolina the well used HW77 was sold due to "lack of use" preferring the lighter R9. LOL....I even bought a .177 HW95 to go along with the R9 and I still own/use both "break barrels". R9 on the left and HW95 on the right............

I kinda wanna ask the diff between 57, 77, 97 beyond the manual in German.
Today my loved 97K-T .20 is taking a well deserved rest from all the successful field target shooting it has done at 27 yards.
In the midst of frustration with the shooting of various rifles today I noticed I was missing more often than I liked so I reached for the cure all: HW80 .177!!!

Compared to my HK 97K-T .20 the HW80 is just as accurate recently!

It may be because in rotating rifles as I always do in a day I find one of them decides to stand out.

Every time it's the HW80--not because it is better than the FWB but because it is an old friend and reliable workhorse. 

Furthermore, it has a right handed stock.  This makes shooting accurately a lot easier for me.

Funny how this discussion drifted towards german rifles. The ones that did the freak out on me when I tightened up the handles on the cocking levers are Hatsan Dominators. But that's ok~ Talking theory and general practice rather than model specific mechanics is what I was after. It'll take me awhile before I can resolve the issues with the cocking levers on these rifles. Now I know how careful I'll need to be so I don't throw off their mojo.

LOL....sorry for the bad feedback since I have absolutely no experience with Turkish Hatsan and the ability to "tightened up the handles on the cocking levers" !

I'm red faced and embarrassed fer sure!
