ok i will admit i am not a skeet/trop shooter.
i just had a customer of mine give me 3 and 1/2 cases of blue rocks. they are older and i think they are blue (i'll take a pic in the am). i'm just curious about them. i plan to donate them to north mountain hunt club near me for them to use in the youth training. i have never heard or seen these things before, so i'm looking for any and all info. thanks rats
my biggest question is do they get to brittle over time and become unusable?
