I have not had time to sit down and figure out all the costs involved so I figured to ask here in case someone else has already done this homework. I have an RCBS single stage press. It's a nice one I got many years ago from an uncle who gave it to me when I purchased his Ruger Super Blackhawk. Almost everything is there....RockChucker loader, Uniflow power measure, a bunch of spare parts, reloading small hand tools and extra primer holding cases, lube pad etc. I also have dies for 9mm, .44, .38/.357. Thinking I was going to reload I bought a nice RCBS reloading scale and a hand primer. But then I never ended up reloading. I reckon to get into reloading .223/5.56 all I need are the dies and maybe a couple of small items. I have everything for my handgun calibers. But my question is........ is it anywhere near cost effective to load for .223/5.56? Given that it's a single stage press and will take a fair minute to crank out 100 rounds or so. I am wondering if it is rather just a way to custom load my own rounds using a particular design and weight bullet as well as a custom powder charge...... that I might not get in cheaper commercial ammo such as Remington UMC or Federal. So perhaps I could save over premium ammo but plinking ammo might just be more cost effective to buy at the store. Unfortunately, I live in Los Angeles so I cannot buy online and have it shipped to me. So I miss out on the sales. The cheapest I have seen Federal XM-193F is $6.99 and I heard it has been as low as $5 and change. Generally I pay $7 for Remington .223 UMC and $8 for Federal XM-193F 5.56. The other Federal with the metal cores is between $169 and $189 for 420 rounds in clips in a steel case but you cannot shoot it at the ranges here. Good for SHTF situation only unless you are prepared to travel a ways to find a place to shoot it. So is anyone loading plinksters for their AR? And if so....... would you re-use Remington UMC brass? Thank you.
