In my traditions inline I use 2 777 pellets and a 245 gr Powerbelt with the green tip....I can stack 3 rounds at 50 yds and at 100yds they group 1"-1.5" with a few touching.......I sight it in so that I'm 2" high at 50 yds which puts me about dead on at 100 yds.....however, it's been about 4 years since I used it as I now primarily Bowhunt....but the rifle is a tack driver with the 3x9x40 Bushnell Trophy on it.....
