why rubberband fx chrony to barrel?

i just put it on the bench, seems to give same numbers either way:

As long as you're shooting directly over it and in the same position every time that is fine. That's how I use mine on springers too. The issue is if your POA changes and the barrel isn't lined up over it the same from shot to shot, you're readings will start to vary some.

i really like the midwest elite airgun picatinny mount.

slides onto the side rail of my impact.

out of the way and does not interfere with the barrel ,win win.

No longer do you need rubber bands or long poles holding your chronograph. With the Midwest Elite Picatinny adapter you can slide your chronograph right on to your picatinny rail.

So that you can point the gun anywhere and it'll read. That's why some mount with the rubber bands.
