HW/Weihrauch HW50s 22 cal

[KWK]

Mate did you get it sorted? I replaced the original seal in mine with one I got from target tune india many years ago when I put in a tbt maxi pro kit. It went from just over 12ftlb from factory to a consistent 10.2 I tried installing a power washer but the rifke would not cock

Is the seal too tight?

I forgot to update you guys. It's shooting low 11 FPE range now.

I just bought HW-50 STL .22 from AOA. I paid for HW-30 STL, .22 but they called me and said that it was out of stock and they could send me HW-50 .22 STL for the same price, if I don’t mind. Of course, I don’t mind.

Is the seal too tight?

It was near identical size to the original one but softer and in better condition. Might be the tbt spring. Might try a vortek or arh kit. Arh was unable to give me a ball park figure on power

I ordered 2 .177s this year. Both were 10.5 ft lbs out of the box. I put Tinbum spring guides and top hats in both, but neither would cock with any power washers installed. Both stayed right at 10.5 ft lbs.

Aren't TBT springs Weihrauch? New HW50's usually run closer to 12 ft lb. Both of mine do. Both 177

Tbt are now producing their own springs. Originally they used OEM hw springs

My HW50 .22 shoots about 11 fpe with 14.3g pellets and is very accurate at that power level
