I am seriously looking at reloading 5.56 for my CZ and AR. (they both take 5.56 and .223) With the price of Winchester 55 Gr. cartridges at $13 for 20 at Cabelas and elsewhere, is it really worth the investment and time ? Can you reload for much cheaper than .65 ?
You can find factory ammo cheaper than that if you look around.
If you shoot high enough volume, reloading could pay off but the payoff point would be several 1000's of rounds per year to make it worthwhile.
Opinions alone don't mean squat, except that of the judge who's deciding your court case.
For everything else you need to do the math:
223/5.56 reloading component cost:
processed 1f brass: $100/1000 = $0.10 per round; with 5 reloadings from each case that's $.02 per round
powder: $40/lb = $0.15 rd
primers: $5/100 = $0.05 rd
bullets: Campro = $60/500 = $0.12 rd
TOTAL per round = $0.34 per round
Those are rough numbers done fast without shipping or tax included. You could find better prices and you might have free brass in hand. But you wouldn't be far off to estimate that components will cost close to $.40 per round. That won't be match grade ammo but it will be as good as the factory bulk grade stuff.
You also need to consider the cost of your additional tooling - dies, etc. If you don't already reload that's a substantial investment and could easily be a deal breaker.
Decide if that cost is worthwhile and don't forget to consider your time because ammo doesn't reload itself. If you shoot enough to make savings of $.20 per round worthwhile then start shopping for components, otherwise just find the best deal you can on factory ammo.
