I am new to PCP airgun shooting, but have an interesting thought that translates from powder burner reloading and tuning. From what I've noticed just shooting the one PCP I have, you have control over a few things to make the gun shoot like you want. Regulator pressure, hammer spring tension, and pellet selection.
This thread will focus on pellet selection and group shape. These rifles are extremely accurate and consistent and seem to shoot pellets very well. Some pellets shoot great. Stealing from Jack Neary's (HOF benchrest shooter) assessment of group shape indicating what you need to do in regards to powder and seating depth can help determine what's going on with an air rifle if used in the same capacity.
So without messing with the regulator or hammer spring and just testing a lot of different pellets and weights, I think you find a lot that shoot well, but the interesting thing to evaluate would be group shape. Size matters
but shape can give insight as to what is going on harmonically with your barrel. Horizontal, vertical, oval/round circle (optimal), diagonal (worst), double grouping; they all indicate what your barrel is telling you it wants.
Obviously you would have to shoot very well to notice the difference in group size and shape, but does anyone have any anecdotal experience with this? Does your best shooting pellet group well and have a round shape to it? Have you tested pellets that group ok but the dispersion is horizontal, vertical, or diagonal? I'm interested to hear everyone's thoughts.
