It's the same vague laws such as "curio and relic ffl may not engage in the business of buying & selling firearms but may buy or sell to enhance their collection"
So if one buys a crate of mosin rifles and keeps the two nicest ones, then sells the rest to cover the cost of the entire crate, is that business?
What about buying an exemplar of a particular pistol in fair condition and then buying one in excellent condition and selling the rougher one for more than you paid but still less than the minty one? You did technically profit.
Generally speaking i would think that a one-time sell off of surplus reloaded ammo as components shouldn't trigger a batfe assault. But if you did it at multiple gun shows and on line for months at a time...?
That said selling reloads to anybody as usable ammo is foolish for both buyer and seller.
