So, how would one go about doing that? My friends and I are into making short "movies" for fun. (really, it is just an excuse to put on the combat boots and the bullet proof jackets and act like we are members of a secret delta force). Anyway, since I just got into reloading, how would I reload blank ammo to use in making very safe "movies"? We have a bunch of airsoft guns but when you want the effect of a mosin sniper or something, not having a huge fireball kinda ruins the film. How much powder do I use? 25% or full power? what do I use to keep the powder in the shell that wont act as a projectile? anyone ever done this before?
