drove 45 miles, hike 1 mile into woods, & after emptying shotgun, my 16 gauge, I find I brought the wrong ammo 12 gauge, I had meant to take it, but changed mind kinda last minute.
also done similiar more than once by taking a pistol & bringing wrong box of spare ammo.
I always have what ever ammo is in the gun, as I never keep an unloaded weapon around the house. you know the saying about unloaded guns.... well I treat mine like they are loaded, because they are, always. been doing it most of my life, & I dont keep anything laying around, in the open, & no kids, & just me & wife. so it works for me.
