As mentioned..Everything..helps to a degree. How much time do you have? How serious are you about making perfect shots? Will it eliminate fliers? Probably not, reduce the number yes, but stop them, NO! Way to many things can cause a flier. Back in my experimenting days I also found that some pellets had off center skirts where the skirt was thicker in one area and thinner in another something few would ever notice but could very well cause a flier! Use good quality pellets and find which are reasonably consistant or spend your spare time trying to improve your pellets. Nothing will stop fliers, but there are many things you can do to reduce the number, which do you want to do? Shoot or sort???
