Ok so the other day I was down in Gatlinburgh and we went to Bass Pro.I was running low on bbs so I picked up some gameface bb's because they were the only ones that looked decent.On the way home I saw that they were Game Face "marker" bbs.They seem pretty solid but they are supposed to leave a white mark.I tested them in my springer because my friend said they werent good for your gun and they seemed to work fine.(Its not like paintball bbs that bust but its made out of a very tough chalk-like material) They only leave a small white mark.Are they ok to use in my guns?
