Worth a try with a pellet like H&N FTTs that usually shoot well with HW100s.

Or you could try shooting into a very deep bucket or barrel of water and retrieving pellets to look for signs of shaving. It does need to be very deep though (probably >24 inches) because otherwise the pellets deform when they hit the bottom.
Me too. Thanks for your useful input.

I have not tried manually loading pellets... I had not thought about it. Now that I do consider it, I was wondering if it would make the possibility of misalignment of the pellet, at the breech end, much more likely. The magazine presents the pellet to be loaded and after the magazine is indexed, the loading is carried out by a pin which pushes the pellet along the axis of the barrel. If that pellet is misaligned during that push part of the loading cycle, it could possibly exhibit some perturbation as it receives the air that pushes it out of the barrel. That could be one reason why all pellets are not grouping whereas previously; all of the pellets did group well. I can ask the gunsmith to look at that issue; thank you for the thought.

I also like the simple idea of test firing the pellets into a body of water in order to see what potential shaving marks are visible. This is another idea I can usefully adopt when my gun is returned to me. Thank you for your assistance.
