Well, today I put around 75 more pellets through the Titan for a total of around 125-150. Its starting to break in some and seems to be settling a little bit. I did most of my shooting at 10 yards and now with cphps I've gotten a few groups under 1/2 inch. I suspect part of the issue was some dieseling early on throwing things off, since I did see smoke coming from the barrel occasionally. I also did a very quick and light sanding of the loading port since cphps have fit so tightly. It seemed unusually sharp and I thought perhaps some burrs were interfering with pellet seating. While still pretty darn tight on the bigger cphps, it seems better now. I think the gun just needs a bit more breaking in and its going to be fine.
