Hey guys, I want to increase the power of the Hatsan 130 .30. I have looked at the Atmos 180 and 190 Gas Rams that are said to increase the magnum models quite a bit. A buddy of mine installed the Atmos 200 and he says with standard JSB 44.75gr pellets he is getting over 50FPE. Now that's something out of a break barrel! Currently using the same pellet I am getting around 32.5 FPE and would like to increase the power to around 40FPE. The gun is hard enough to cock as it is so increasing the power by a large margin isn't really appealing. My gun is a coil spring Canadian version that does not have the QE system in place but was replaced by Hatsan's front sight with cocking aid. I want to know if adding steel washers would increase the power and how many to add. I was thinking 2-3 washers if that would increase the power at allAny help would be appreciated
I DID read about someone who STARTED with a Mod135(?) rifle and CREATED something amazing that was at or above 50 fpe. The article (I'll post a link if I can find it again) went on to claim the rifle was the most powerful of it's kind.
