I'm getting a 37MM soon and I've been finding it hard to locate in depth reloading guides for different legal 37mm munitions. Mainly I'm trying to find info regarding how much and what types of powders are safe so I can be confident that I'm not going to blow my hand off.
I've found that guide in particular which says to use between 40 and 80 grains (volume measure) of black powder, but i've seen some guides saying to only use 20 - 40 grains. Anyone got any experience with this? I wanna make some fun flares, smokes, and chalk rounds without overdoing it and blowing my launcher up.
Can any guys who have a bit of info throw it my way?
