Ty, that's why couldn't find anything.You can't find 5.56 dies, because they are the same thing as 223.
Yes, you load them the same.
If you want some actual detail:
Read Post #35 in this sticky, by UncleNick. And I've got a thread where I called and spoke with all the domestic manufacturers, who specifically told me there is no spec'd difference in the brass.
Both shoot both, and is shown in the pressure tested reference in Nick's post. 😉Mine say 5.56 but shoots both ty
Somehow it seem's this suggestion escapes a lot of people and I'm not sure why. Specifically "start at the start load and work up"! That has got to be one of the most basic rules of handloading!5.56x45 and 223 Remington cases are for all intents and purposes interchangeable. The difference between the 2 can be found in the chamber of the rifle, which if you follow proper reloading procedures, does not create any issues.
You can use 223 Rem data and dies with 5.56x45 cases. As you should always do with any different lot of cases, start at the start load and work up.
I have checked my cases several times and seen numerous reviews on difference in cases for 223 and 556 and the data shows that there is little difference in case capacity and the slight difference shows the military brass to have a slightly higher capacity than several commercial 223 brass.
Yep. The military being thicker and heavier applies to 7.62 NATO vs. 308 W. I have 308 cases as light as 153 grains and a foreign 7.62 case that is 185 grains and am pretty sure I once had one that was 190 grains. A total brass weight difference of over 30 grains. If the heads all had identical dimensions and if the brass alloys were all the same, it would represent a difference of almost 4 grains of water capacity, though, in reality, none of those other things are all the same, so you actually have to measure case water capacity to see what you have. But for 30-06, the difference is more like 10 grains of brass. For 5.56 vs 223, the common commercial brass is often about 4 grains heavier than Lake City. I don't know what the newer Starline 5.56 brass with the harder heads has by way of capacity.
First what are you shooting these rounds out of? Second 5.56 dies you can get from RCBS. If you are putting these through an AR then some ARs require you to use the 5.56 dies even if you are shooting .223. Reason being that the ARs are requiring the .223 bras to be squeezed to tighter tolerances. My Colt will not accept reliably .223 brass reloaded using .223 dies. But always accepts .223 brass from the RCBS 5.56 dies.I have a bunch of 5.56 and was wondering if I can use my 223 dies? Can't find any 5.56 dies. Also do I reload same as 2.23? Tyvm
