I have a Titan XS that I have been trying to get to shoot respectable groups. I did the CDT super tune on it and while the cocking and firing cycle does feel much smoother, the groupings still leave much room for improvement. So I decided to check my barrel by pushing a pellet through it. The first 1/3rd section feels really tight and uneven. After that it gets much more loose and by the time it reaches the end of the barrel, the pellet pretty much just falls out. I've read that a good barrel has a bit of a choke near the end. So if I fire lap this thing, the first will open up but so will the end section. Is there any hope for this barrel?
