My biggest concern is safety while working with the powder, but I am sure it will be covered in the text.
I'm sure it will. Smokeless powder isn't black powder. It is very hard to set off, and basically just burns slowly if ignited in a pile.
Primers are the thing to be a little more careful with.
Also, there are many dangerous things which can be done with powder other than handling it, which isn't dangerous. The
quantity of powder (the charge) is extremely important.
Too little (for the weight and style of bullet you are using) and you can get a squib, which means the bullet doesn't come out of the barrel. A subsequent round may chamber and, when fired, it will destroy the gun. Probably injure the shooter as well.
Too much (again, for the weight and style of bullet you are using) and you can get an overload, which means the pressure developed is more than the barrel/action is designed for. This can also destroy the gun and injure the shooter.
Follow the load specifications and get your process down so it is repeatable. Think "quality control". Uniform and to spec = safe loads.
