I took my .30 cal out today to make a range card after being tuned by Bwalton. He tuned it to 930 - 907 FPS for 10 shots, increasing me to about 85 FPE. The video below shows the difference in power as these 44.75gr JSB pellets collide with their targets
See video link below and again, thank you Bwalton!!!
