Has anyone done a side by side comparison of FX slugs and JSB .22 18 gr pellets? Specifically if no changes to the reg setting and with out slug liners. I would like to be able to switch back and forth between the two but not sure if that works. For 90% of my shooting JSBs are great. The question is does it make sense to keep some FX slugs around for when I need them (long shots, windy days or when I need extra killing power).
