Recently I've been experimenting with light weight bands, and seeing how much speed I can get out of 8 and 9.5mm steel, shooting both full butterfly and short draw. The following are the results.
GZK green .54, short draw, 9.5mm steel averaged 304.6, with 310 fps being the highest speed.
Precise yellow .5, full butterfly, and 9.5 was almost 20 fps faster, with a top speed of 329 fps.
GZK green .76, short draw, 9.5mm was surprising. This is my current short draw hunting setup. This speed was on a cold shot, but I'm highly impressed with a 326 fps cold shot.
I only tested the 8mm with the Precise yellow .5, and holy cow is this stuff moving! The first shot with it measured 356 fps, with the final shot moving at 367 fps!
The frames I used for testing were as follows
LBS mega - full butterfly 22-13 taper
Simple Shot Hairsplitter - .54 short 25-18 taper
Simple Shot Scout XT - .76 short 25-15 taper
All tests were done on a windy, cloudy day. I'm anxious to see what these setups will do on a warmer, calm day. I believe the Precise+8mm combo will break 400 fps. Speed testing is one of the only ways we can really calculate performance, and with these speeds we can all see that these light band sets are actually moving the ammo effectively enough to kill anything within reason.
