因為果日我係用Thompson, 全自動, 原裝好似得60粒...全自動點數???
If you use the gun usually, u almost know how many bb will shoot in 1 sec., and u can control how many sec. u will shoot each time, so u can count how many bb in mag.
eg.
5 bbs per sec,
shoot 2 sec. each time,
so you can almost shoot 6 times(60/(2X5) = 6)
That's very easy, and I always do that.
