May seem like an odd question but I'm working on an ammo box that can substitute as a loading block and block at the bench. Thinking of using some magnets in the construction and was wondering if anyone knew of any adverse affect a magnet could have on a fully loaded round.
Lots of loading blocks with hinged tops have earth magnetes in them. Static is your enemy, not magnets. Also, remember to have a recess or hole where the primers in loaded round will set.
