12 ft/lb Weihrauch springer?

[Deerstalker]

These are my chrono #s for my HW95L .22 after about a year with an ARH kit, Vortek seal & GPL-205 lube. Probably 3K to 4K pellets in that year. Rifle is soundless for the cocking cycle until the piston latches onto the trigger.

I do find mine to be a bit more hold sensitive than my HW97 K. Still, with the JSB Exact 8.44 pellet I’ve been shooting eggs at 40 meters easily. It is also a lot more prone to windage issues it seems. Any little puff of air blows those .177 pellets around a bit. 


Out of mine; H&N FTT 4.51 and JSB Exact 8.44/4.52 are absolutely lasers…when I do my part. 


I do have an ARH full power kit on the way and I’m looking forward to tuning it myself. I’d like to be right around 10-11 ft/lbs for a sweet <30 meter small game killer.

good luck with yours!

Great plan. I do most of my hunting with a 10.5fpe hw50s in .177 and it is quite effective. Mine had an ARH full power kit and that gave me about 11.5fpe with the JSB 8.4s. That was too fast/jumpy and I plan to cut a coil or two and bring the power down to between 10-10.5fpe.

Although I do prefer the shooting characteristics of the ARH kits, I gotta say that Vortek wins by a mile when it comes to ease of use. The top hat design used by Vortek makes is very easy to clip a coil and adjust power. Clipping a coil on an ARH spring is a much more complex process because you need to use heat, close the open end and then likely grind it flat so the top hat fits.




You answered my question. That is exactly what I plan to do.
