Thanks Guys. I wanted to share the Trajectory MAP that I have developed for the gun so far in case in might help someone. I have the Centerpoint Adventure Class 4to16x40AO Scope mounted using the rings and mounts that come with the scope along with the Benjamin by Nosler 145gr Ballistic Tip Air Rifle Bullets available through Crosman. I like to take my 5 shots between 2700 and 2200 PSI. Each shot drops the PSI about 100 lbs then after 5 shots I top it back off to 2700 again. This seems to be the sweet spot on the power curve. You can get 10 shots per fill if you fill it up to 3000 PSI and shoot it down to 2000 but I like to find the sweet spot and stay closer to that. I don’t have a chrony to test this theory this is just from shooting about 300 rounds through the gun now. Here is the MAP I have so far:
The Trajectory Curve topped out at 25-40 yards so I made that the DO (Dead On) and all of the other yardages are holdovers using the Mildots below the Crosshairs. I plan to sight in every 5 yards out to 100 or until I run out of Mildots first. I wanted the gun to be able to take turkey next spring at 5 yards so I wasn’t so concerned about making this a 100 yard gun although I do feel it is capable of being accurate out to 100 if you wanted to sight it in for that far.
