Well well you have what I have and in the same caliber but mine's the Thumbhole stock in Beech.
Look at what YOU did with the .20!
I have said I'd be willing to sell my .20 HW97K-T but it won't happen because I know in experience with it it is better than anyone else's shown with targets and such in .177 or .22.
The reason I am willing to sell my own HW97K-T .20 from years and years ago is because I got an HW98 .20 and THAT is NOT EVER going before the vaunted HW77/97 or any other underlever made by anyone.
The only reason I keep mine if for REFERENCE to the fact the HW97K-T is more accurate than anyone else's HW97K-T in .177 or .22.
So for me it is a reason to PROVE the .20 is really the best caliber in most air rifles.
As well, for personal reasons and the amount of time and years I proved to myself anyone liking an underlever for any reason should try the HW98 and compare. Whether they shoot off sandbags or offhand. The HW98 is the rifle to end it all.
"Just end it and get an HW98" is truly my first suggestion for anyone wanting consistency, longevity, accuracy, and life-long BONDING to the rifle. Every HW98 I have is an absolute gem. I have them in .177, .20, and .25.
But I KEEP my HW97K-T .20 that I bought from Straight Shooters many years ago when it was Craig and Kevin.
It is a GOLD star rifle, admittedly not as good as any HW98, but admittedly probably the best kind of underlever today.
And it is better than the TX200!
