for what it worth, I've been reloading ammo for about 7 years, just shoot me a pm with your address and I'll make you up some dummy rounds, ie no powder and primers. I can get you some 308, 223, 300 win, 30-60, etc..
Also again for what it worth, your computer will never get hot enough for the rounds to go off, the only way they will if your rounds on top fall off and the hit the rounds below, ie if the bullets or anything get their primers ruptured. most 223 rounds have a harder primer installed as the 223 has a free floating firing pin in it, so it's really not that much of a concern. if you have match ammo that your using ,then typically a match primer / softer one is used . = more concern..
this is all of the stuff it takes to reload one caliper, this is some 300 win mag I loaded up for a 1000 yard match I had
Here's my typically reloading pile, with two kids, I do this about every 3 months.
either way.. Looking GOOD!...
