First black powder certificate inspection

[Turnup]

I’ve just received a call for an inspection for my first black powder certificate.
I have the correct box that is locked and hazard marked unsecured in a bedroom wardrobe.
Would that be ok?
Also should I get an anti-static mat for reloading my 45-70 with bp?
I had been using 777 in my Remington nma, but that now needs a license.
Thank you

Forces vary in their expectation for security. Mine requires the box to be secured in a way that allows it's easy removal by the owner (in case of fire) and this usually means chaining it to something with a padlock.

Anti static mat - never felt the need myself provided the powder handling tools etc are made of suitable materials. I don't think that 777 is static sensitive, it can't hurt though. Think about how you will deal with the inevitable powder spills.
