As Joerg points out, it doesn't pay to stretch bands beyond 4.7 X 71 M/s (~270 fps) because it shortens the life of the rubber.

Tubes last longer than bands.

What is the best that we can do with tubes?

What is the fastest you have shot tubes?

Was it a single color or a 'tapered' combination?

Yesterday, I shot a 5.2 gm marble at 234 fps using black Thera-Band tubing.

I wonder whether anyone has shot a Thera-Band tube faster than 234 fps?

Did the tube last for many shots?

It seems to me that tubes and ratcheted rifles are a good combination.

You can draw tubed rifles harder than slingshots and shoot them with greater accuracy.

I know that the trumark black bands and the red tapered bands both claim more than 250 fps. Other than that I am not sure.

I have never shot standard Trumark tubes over the Chrony over 180/190FPS. A more common speed for Trumark tubes shooting a 7/16 lead ball would be 160FPS. That will generate 7.17 foot pounds of energy witch is enough to kill small game. Tubes don't last much if any longer if shortened to shoot the same speed as flats and have a lot more recoil. Recoil is unused energy that will go directly into your arm (wrist and elbow). A tube is not a very efficient shape for slingshot rubber, but is easy to buy and use. Trumark tube assemblies are probably the best shooting tube assemblies out there right now. A standard straight tube assembly will shoot about 145FPS. Of course speed varies with the draw length. -- Tex

personally i would rather less shots with powerfull flat mands than a thousand shots with less able tube bands. but then i have the luxoury of trade price bulk materials.

I guess 9.7 FPE at 234 fps using Theraband Black within 4.7 X is not too shabby.

The Boynton-Banger has little, if any, recoil.

I would like to see 300 fps with 5.2 gm marbles.

Longer draw makes for faster velocity, but don't over stretch the rubber unless you want to shorten the band life. It's somewhat faster but less efficient to over draw.
