I want to start off by saying than you to everyone for all their input. My plan as of now is to go to the 50' indoor range that is available to me and start there. If I am seeing improvements I will keep working on the task at hand. If I don't, I will start at a shorter distance when the weather cooperates and if shorter distances don't help, well, I will have to make some decisions. I shared this with Roadworthy: When I first got this rifle I didn't have this much trouble. I sighted it in, was happy hitting cans at 30 yards and killed a couple of groundhogs at close range, less than 50 feet. Two winters ago I brought the Trail NP Xl with me to a sportsman's club I belong to with a 50' indoor range. It was all over the place. I found the rings loose and tightened them up and did the ball bearing modification on the trigger. Trigger was better, but not great and still no accuracy. The rifle sat. I decided to play with it again this year, but nothing I tried seemed to improve the accuracy. I kept telling myself, self, your not this bad of a shot. So, I figured the scope was bad and threw the Center Point in the garbage. I replaced the the scope and the trigger while I was at it and went for 50 yards thinking, what could go wrong? New scope, trigger (which is a lot better!) and high hopes still didn't make the cut, but I am finding out that my skills at 50 yards with this rifle might be the problem.
I must second the advice to follow through. Try to watch the pellet hit the target through the scope. Concentrate on that and much of the other will fall into place. Lots and lots of trigger time without a lot of information overload.
I have a Benjamin Trail NP XL .22 that is frustrating me. I can’t get this rifle to group. I have shot 350 to 400 different pellets through the barrel. I replaced the trigger with a Charlie Da Tuna GTR-III and the scope with a Vortex Diamondback Rimfire that has a set 50 yard parallax. I wonder if it tore up this scope too. The darn thing just doesn’t seem to group or track right. The trigger feels great now and I thought would help as with any rifle with bad trigger, but it is either me or the rifle that is still awful in accuracy. I am going to see if it is any better around 35 yards or less, but I am ready to give up on this rifle. If I can’t get this rifle to be accurate between 35 to 50 yards I wasted quite a bit of time and money trying.Truth be told I don't have a lot of experience with air rifles. Maybe I am just expecting too much out of this rifle.
What strikes me most is your statement that you shot the rifle well or at least better when new. Almost all of my Crosman rifles were bought on the extreme cheap, because of some one else's problems and the resulting frustration....I have seen pellets hitting the shroud, bad shims at the barrel joint... I haven't had a bad crown but almost always the seal is bad or questionable. The stamping process leaves very sharp burrs and the seal winds up cut. Deburring and a new seal cures this. ..The first Crosman NP rifle I bought years ago, was a Titan which was a great shooter. I put a Charlie trigger in it right off. Tack driver, but then the accuracy died. A new scope didn't help. End of the story is a bad seal....I still own the rifle and it is a sweet shooter....As far as high powered springers go, I have a Diana 48 and a 350 magnum. The 350 will run with most of the best but if the hold is consistent it is amazingly accurate. I have never owned and shot a Trail XL but have a couple Trail NP2's. I think the XL should be able to shoot better than say the 350 because the 350 uses a long spring and has the resulting torque....I will get one someday and explore my theory....
