I purchased the above off the forum . I recently had it chronographed this Wednesday in fact . It's had a new seal where you fill up . It's in .22 , I'm shooting .22accupell these were chronographed at 3.1 foot lbs . I think the pistol should be able to do 5ft lbs as stated by Brocock . I tried to ring them but to no availe for general public . I've been online . I need to know where I can get a exploded diagram for this pistol . It's a single shot and not the new magazine ones . It's not the Pistol where you can turn the screw at the back to adjust the power . Any help please . All I can do is ask you. Chaps . Many thanks if answered . Regards terry
