A million dollar question...
Golfer, KBLB has never published performance specifications on DS, DS 2.0, or their other recent silks beyond a single report of a small sample which had a strength rating of around 2 GPa. We don't know how representative that sample was or have a stress/strain curve for the silk. The Army tested some strands of DS and then requested a stronger silk, suggesting DS was not sufficiently strong for their needs. No performance tests hand been reported on the shoot pack(s) delivered to the Army.
We are in the dark. Still...
