Recently competed in a rimfire tournament and had a lot of FX Impact M3's present shooting the 50 yard bench. Almost everyone had a barrel band on their .22 shooting the Altaros 40 grain kings. I never tried barrel bands but they all stated that it makes a significant difference. Anyone else agree? They were grabbing theirs from Tremor Air-guns. Has anyone tried these barreled bands and are barrel bands that affective?
