Hatsan Hercules Hammer Spring

Greetings everyone

I have a question regarding the Hatsan Hercules in Larger Calibers

Has anyone ever cut their hammer spring down a little bit to prevent injury while cocking the Rifle

My Shoulder hurts severely when Cocking mine. I have taken this Rifle apart so many times

and no matter how many turns CCW i do it really hurts bad.

So if mine is .45 Cal approx 290 Fps 850 fps

how much Foot pounds would i lose if i cut lets say 3 or 4 coils off?, and approx how many FPS would i lose

has anyone ever done this on a large Cal Hercules?

Or is there a Lever Mod that I can do to make my Lever have more leverage or larger handle?
