Got the new liner and now to put some quality time over the chroni and see how the NSA slugs will perform. Will post some speed and accuracy info this weekend.
Which weight .25 slug is achieving a BC of .09? I wonder if the lighter NSA .22 slugs showing a BC of .075 but with the ability to get higher velocity in an FX Impact might be a better choice for longer range shooting. They are lighter than .25 slugs so can achieve higher velocity while consuming less air. At some point down range the veocity of the higher BC .25 will catch and over take the .22, but at what distance. The .22 slugs seem like they might be more efficient for longer range targets but the .25 slugs will carry more energy for hunting purposes. There is so much to consider and think about. What a Great time to be into air rifles.
