Rubber Band Follow-up

Cro took it out to the range again on Sunday and put another 250 rounds through it.  I asked what happened, did it just loose it's bounciness? Melt into a puddle of goo?

nope, I ran out of ammo at the range.. didnt expect it to last that long, it was just way too dirty, when it got hot from rapid fire the polymer cases melted.. but its still going strong

(He was referring to the polymer coating on the Tula rounds he was firing.)

Really makes you wonder...
