Okay now we busted out the chronograph and arrow scale. My Easton Axis ST 340's cut to 30" with a 100gr field tip, nock and vanes weigh 433 grains. I know, kinda on the heavy side. Shooting through the chronograph I shot 284 fps with a 30" draw set at 70lbs and an 80% let off. Once again (unlike what I've been reading), I'm shooting dimes at 20 yards. My grouping is pin point. Now over time who knows? For now, I'm giving the Easton Axis ST 340's a two thumbs up. Hope this helps some of you that have been following my trials with these arrows. Till next time..........
