have been trying to develop some bands that will zip a 7/16" ball out of a traditional style fork at at least 300 fps. It's fairly easy to achive this kind of velocity when shooting light projectiles from extended forks. I went out this morning and shot a few rounds over the chrony with a new set of bands I tied up last night. It was kinda cool out. the first few shots ran around 200ish, but after a few shots for the bands to get warmed up it upped to 295, 308, 319, 331 and so on it kept most of the shots in the 295-325 range, I was overjoyed to see this. the bands I am shooting are dobuled .050 latex cut on a slight taper. These velocities were achived at an ear anchor, my standard achor point, I did a longer anchor behind my head and got two velocities, one of 475 and 500 fps! I know a couple shooters that anchor back this far, but I do not shoot this way.

Welcome to the 300 club CK! Wow 475 and 500.I never hit that speed,especially with a 7/16" steel ball.Heck,I never hit that speed with a BB! You're running double 50's on a mild taper and getting those speeds? Man,I have to re-try the 50's! Great work! Flatband:)

I consider them a mild taper, considering the drastic tapers I usually cut. The 475 and 500 shots I anchored way back, I've only seen a couple people that actually anchor that far back. Trying out some new rubber in the morning weather permitting, single layer to see if it's suitable for hunting.
see ya

not so sure of the velocities now, my chrono isn't giving me very consistant readings. I think my chonry may be toast, I will get a new one soon and try to confirm velocities. sorry for any confusion
