Be very careful with dippers
I got a couple of dangerous squibs when I under loaded a different type of bullet than the formula called for.
As a newbie, and I still kind of am one, I didn't realize that bullet type mattered all that much and used a dipper that corresponded with bullet weight, but not bullet type. The result was a very dangerous squib in a revolver and an hours work at home taking apart about 150 rounds.
If you use a dipper follow the formula exactly, powder type, bullet weight everything. Course you should do that even if you don't use a dipper.
Live well, be safe
