I've been getting 65m plus. Little used original stock HK red 10m 6/4mm. I guess 30 paces is approaching 3x stretch.

Nice launches :)

The 300% stretch factor (called extension in the spec sheets) is interesting.  The balance is between maximum extension and maximum load with a curve that optimises total stored elastic energy (integral of load as a function of extension, or roughly average load x max extension).  

Do you know the pull (in kg or lb) at 300%, @StraightEdge?

We are still on the 3rd challenge until the 26th - unless someone beats the current target. Looking at the forecast, that is looking unlikely.

Hi Pete, I don't know the exact pull stats for my particular length of original HK, just go by feel.  Can of course get a fisherman's scales (or whatever they're called).

Apologies. I did indeed miss this despite getting a mention. I was on holiday last week. Must have left my brain behind. 

I'll update the tables.
