30 cal cans for me. 50’s for storage long term, transfering to 30’s for range time. Some time back Trapper and I were going to a revolver class in Sebring area. He had his suv hatchback. I had metal cans, he had plastic cans. Somehow he didnt secure the hatch and coming out of my development he floored the audi and we heard a noise. He pulled over (5:30 on a sunday), and found his plastic can on the ground with 500 rounds of 45acp all over the road. My can was intact sitting on the pavement. Fortunately it was early on a sunday and traffic was non existent. We scrambled around picking up ammo, laughing, and got it all up pretty fast before any cars came through. That incident alone convinced me that metal mil cans were the only way to go……..
