my problem with thin sling line's is they tangle to much.
now for myself I have solved,that problem. I made some sling line,s braided out of spider wire. Then sprayed them with three coats of lacquer,makes them nice and stiff.
And for me they dont tangle. Here's a pick of the latest sling made that way

One could tow a small car with the amount of 'spiderwire' you have shown.  

The advantage of such material over others is it's low stretch and smaller diameter per given strength.  At such a diameter as you have there, nylon would certainly suffice in both strength and stretch factors.

To take full advantage of spiderwire's small diameter and coefficients of drag....one simply need attatch or tie a cord 'retention loop' in or on the retention cord near the hand grip through which passes the release cord, such that the release cord is prevented from slipping through on release.  Leaving enough room, of course, for the release cord to slide through just enough for the pocket to fully release the ammunition.

This allows one to use the most efficient cord possible without fear of entanglements as the release tab/point always stays near your hand.  It is advantageous as well, to use a retention loop or small washer to keep the cords in contact with one another down near the pocket as well and also provides for a more secure purchase on the ammo.

There are a number of benefits to such a system.....not the least of which is the ability to reload the pocket very quickly with even a minimum of practice.

Lobohunter, you stated:

"But we are all not you."

Come on......not even a little bit?  

No,  I read you.  I am sure I often times come across as a 'know it all' regarding the sling.  ( I learn new things all the time....part of the reason I love it here.)

I'm sure that if you do not take my factual remarks too personally....you might learn from them.  It is of no personal consequence to me whether or not these advancements are emulated by others and they are offered as suggestions, rather than commandments.  Being ultra utilitarian by nature....I can understand how naked fact can intone derision, where none exists.

Thanks for the civility check, though.  I could brush up on my etiquette.




P.S.  I wasn't joking about towing a small car with the diameter of aramid fiber that is shown.  I hope that my statements were comprehensible about the performance advantages of release cord retention over thicker, stiffer cordage.  

tried the retention loop, nullifies my wide grip.
makes my pretty spirals go away thanks Techstuf
