Some years ago l reloaded a 50 round box of 38SPL ammo that had ALL the primer holes plugged with walnut tumbling media. Ran them and a control box of 50 without plugged primer holes from the same batch over the crony the same trip. I found NO difference in any round beyond a normal SD of each box. If that is not going to cause problems l doubt a few grains of propellant will be a problem either. I store my ammo in quart freeser bags inside of 50CAL ammo cans without issues.YMMV
