Hi, I tried them on a coke can at 7 meters with a 400fps WE SCAR to compare them to my .30g Madbull bbs. I was very deceived because they simply bounce on the empty coke can compare the the .30g bbs that pass threw it. I though they were carrying more energy on impact, not that they would bounce on it? For me, as a result, far less damage done to the coke can compare to normal bbs...
