New here, any brocock fans in here! Ive got some work done. External plenum, lightweight ssg hammer with peek striker/plunger, huma bottle reg, and some porting for now. Ive got some different tunes, accuracy tune is jsb heavy .25 34gr at 940fps. Holds moa at 100 most days. And a hunting tune with 43.5 nsa slugs at 900fps. I get 50 shots on the accuracy tune and only 20 on the hunting. Id love to see what other people have! Dialed back to 40ftlbs it gets a rediculous amount of shot with jsb 25gr.
