Finally found the right setting for this gun, in .177. I wanted about 800fps for backyard use, factory it was shooting 940fps. I replaced the regulator with a Huma, set it to 100bar. Replaced the hammer and spring with the lightweight hammer and upgraded short spring from Apex Airguns. With the spring backed out all the way and shooting H&N Baracuda 10.65gr. it shoots a consistant 800-803fps for 88 shots before falling off the regulator. The last two shots out of the last mag. still go into the group so I am calling it 90 shots on a fill. Sometime I may try turning the regulator down to 80 bar and then adjusting in the hammer spring and see if I can still get the 800fps with a few more shots. Not sure if it is worth the trouble, I am happy with 90 good shots on a fill. Was a bit windy today to check accuracy, have to wait for a calm day for that. When I shot between the wind gusts though the pellets did seem to go where I wanted. My backyard range is 35 yards.
