I have been experimenting with graphite and PTF wax and powder on the slingshot rifle pouches. It helps improve accuracy dramatically.

I found a method of measuring the friction coefficient of my pouches.

44151



The first pouch Top: is Canvas/microfibre laminated without any wax or powder. Pulling the stack off batteries produced a result of:

0.16lbs (72.57grams)

The second pouch is 420D Cordura Denim ripstop fabric/microfibre

The result was

0.12lbs (54.53grams)

The bottom pouch is canvas/microfibre that has been treated with PTFE wax and additional PTFE / graphite powder rubbed in with some leather.

The result was

0.06lbs. (27.21grams)

Amazing nearly 300% more efficient than the untreated canvas and 200% better than 420D Cordura Denim ripstop.

The stack of batteries weights 0.5lb's (226.8 grams).

Here is the video discussing the formula to Calculated the static friction coefficient of a object.

These pouches are for use with this style of mechanical release: The pouch die used is a s165 from slingshooting.com

New guy here, please tell me more about lubing your pouches.

My primary goal is greater accuracy. Added velocity would be a welcome, if unintended, by product.
Do you recommend a paste, or more of a liquid product?
Saturate the pouch?
Have you tried lubing the projectiles instead of or along with the pouch?
I can imagine trying to handle BBs and ball bearings after treating them...

My thanks for bringing out something I'd never before considered!

Second thought. While looking at PTFE on line, I found a product in my workspace, a roll of Teflon tape.

I plan to match a regular leather pouch against a similar leather pouch lined with the Teflon tape and check
for accuracy. It occurred to me that a lubricant soaked pouch might stain my clothing.

interesting concept - may have to experiment with applying some paraffin wax to the inside of my pouches. Downside - if any wax got on the outside (grip side) of the pouches, that would be disasterous ..
