I changed my TP and cleaned my barrel, as well as polished the crown, port, and bore. Put it all back together, and even though it was grouping a little tighter, the POI was still shifting with all ammo types. So I decided to fill the gun to about 2700 psi and shoot 25 pellets to see what would happen. First shot landed right where I wanted. The second was half an inch right. Next was half an inch high. Fourth was about a quarter inch left. Then a quarter in right. Then high. Then dead center again - for the next 15 shots! Then it began to wander again. So, I pumped it back up to 2700 psi and did it again, and it did the same thing - danced around the bull for about 5 or 6 shots, settled in for about 15 shots, and then began moving again. So, it would appear it is being pressure sensitive, and my gun groups best between about 2550 psi and about 2000 psi. I was hoping to get more than 15 usable shots, but it beats the shotgun pattern I was gettiing yesterday, that's for sure! Does anybody know of a way to make it less pressure sensitive? If not, I'll be okay with what I've got.
Thanks for all the help,
