Thanks Brother,Wish this thread had been left on the general airgun forum to get more traffic, ....Ho well Just started my 1st battery of testing and accuracy, downloading pictures right now.
If you don't mind me asking, what was the yardage you were testing at?
If you can get some of the new Crosman Piranha pellets, mine does a little better with them than the CPHP.

Have you been able to lighten that 1st stage ?do you have some real world FPE on this gun ?
Quote from: Nomadic Pirate on January 30, 2016, 07:13:17 PMHave you been able to lighten that 1st stage ?do you have some real world FPE on this gun ?I adjusted all the first stage out of the trigger on mine so I feel the "wall" when pulling the tigger back. The release is crisp at that point. YOur mileage may vary.I ran JSB 15.89, H&N FTT, CPHP and CPUM pellets across the Chrony on Dec 14 & 26, 2015, and the JSP was at 19.02 FPE, but the rest were 20'ish FPE. I ran Chairgun Pro and found the FTT to have the best retained energy at distance/speed at 20 yards. That's what I've used for hunting squirrels.I ran the NP2 across the Chrony last night, and I have a problem. The speed has gone down significantly since the last data capture. Cleaned the barrel and did the tissue test at the breach seal, and all appears normal. Without changing the o-ring I won't know for sure. The same thing happened on my Trail NP, and Crosman exchanged it for the NP2 because they were sold out of the Trail NP, and was only through Chrony data collection that I found out last time. The accuracy is still there, but losing FPS as well as retained energy at distance. (I'm not a very good shot, but the groups are pretty good for me.)I have the POI about 1/2" low at 12 yards (my basement range) based on the Chairgun data for the FTT. The JSP is also close to this mark, so you can see the accuracy is not lost, just the speed/energy.Calling Crosman this week to see if I can get an o-ring to see if that's the problem.EDIT: Here is a chart showing how much energy is lost due to speed loss.
Manny it doesn't matter where you post you have a following sir. David

DavidMaybe,...but this thread would have been better if it stayed on the Air Gun gateHere is kind of relegated to where people just go and check reviews, over there it would have reached a bigger audience......Ho well.
Manny - you do not need to remove the stock to adjust the trigger screw. There is a hole in the trigger guard. Joe - It sounds like yours has a seal gone bad. Mine started at 815 fps. It dropped suddenly to 730 fps. It was the ram. The NPSS seal from Pyramyd is the same.
