So we got some of each to test them in the space. The CA blanks were half loads, and sound-wise were almost too loud. So we got some quarter loads from CF, thinking they would be quieter. But it turns out they were actually louder, even though they were quarter loads. It's a good thing to know that there is no actual standard when it comes to the strength of blanks.

It's always a good idea to test the weapons to see where the danger zones are. You want to establish where the force of the explosion is being expelled so that you know where an actor shouldn't be standing. Testing the weapons is a simple procedure.
