Weihrauch HW97kt

[Pelletsmasher]

Hello again everyone, I recently purchased the Weihrauch HW97KT Blackline in .22. So far this rifle is fantastic! I have about 650 rounds through it so far and from what I have watched on You Tube and what I have read suggest that break-in period is around 200-300 shots. Mine is still dieseling after 650. Everything is coming together and it is smoothing out. My question is, those of you who own this or similar guns, Did you disassemble the gun and tune it? I would like to do this just to get rid of the yellowish Vasoline type grease Weihrauch uses. Also I have the full power version (15-17FPE) is there an upgrade kit available or even a spring that will give maybe 17-19FPE?



This is my rifle



Thanks



Ian

Have you been shooting it on a downhill angle? My new 77 was dieseling after 250 breaking because I wuz shooting down on the lawn from 3rd story.

Hello everybody. Look up the “Vortek” spring tune kit for the 97. Easy to disassemble. I made a spring press with a pipe clamp. Used it for years. The rifle with the tune kit in it is unbelievable. It will never achieve the same behavior with the factory spring no matter how many shots are put through it.

Thanks all.

I love my thumbholes. 

 3-97’s and a 77. All deadly accurate. Hopefully will be putting kits in all of them this winter. Crow

The factory Weihrauch spring will outlast all of the aftermarket spring kits, as a general rule. If one wants the best of both worlds whether budget minded or not there is a great 3rd option. Dismantle the gun, clean and polish all intervals and fit a piece of blister pack plastic in the piston that just snugs the factory spring. Thickness of the blister pack is essential. Takes some experimentation with different plastic to find the perfect thickness. Polish the ends of the spring to a mirror finish. This will aid in the spring turning and not not binding as it is being compressed Put a generous amount of spring grease on the spring to dampen any other spring noise and help guide the spring in and out of the sleeve. This is really all the over priced tune kits are. Perfect fit to spring and sleeve. When cocking the spring goes straight back and when firing straight forward. The twang is eliminated. The spring will last longer because it is not taking a negative set and being stressed with the twang. The twang noise is an indication of stress on the spring. Put only one drop of spring piston CHAMBER oil on the face of the piston seal. It is literally impossible to under oil the chamber but most over oil. Over oiling causes dieseling. Maybe even chamber ignition which can break the spring or damage the piston seal. Do not over oil. No oil is better than to much. The seal is nylon and no metal to metal is going on. The oil gets in the parachute of the seal lasts a long time.
