How pedantic are the police and more importantly dealers re the description of a firearm on an FAC.

For example can say I want a muzzle-loading pistol in order to choose between a single shot pistol or a revolver like a colt or do I have to say one or the other.

Like wise for a rifle do I have to be more detailed and state bolt action or semi automatic?

I am just filling my form in and want to get it right.
