    Why can only find reloading data for .223 Remington but not the 5.56 NATO in my Lyman and Hornady reloading handbooks? Thanks.

    There is only .223 data in reloading manuals. .223 and 5.56 rounds are the same. It's the chamber specs that are different. The differentiation you'll find is data for gas guns (ARs) and bolt guns in some manuals.

    Are you trying to duplicate M193?

    Same round. As zombie stated are you trying to mimic the NATO ball? If not just use load data for .223. 6mmbr.com has good info on .223 5.56. If you need any other help let me know, i am getting pretty good with the .223.

    I was possibly gonna buy some 5.56 for my Bushmaster for a change instead of .223 and was curious if I should reload or toss, but I can't find the much needed data. These high pressures can be a lil intimidating when reloading if you know what I mean. Yes, I suppose I could always load as a .223

    If you are going to toss them, i will pm you my addres. :tongueout: just buy the 5.56 and reload them just like .223. 5.56 can have less case capacity due to thicker walls. I have a ton of 5.56 and load them just like .223, but they may have crimped primer pockets and you will have to swage them first. Just make sure your bushy is chambered for 5.56, but i think they all are. :dunno: A good load me and XDRoX have found is 55gr fmjbt 24.5gr of Ramshoot TAC CCI #400 SR and a C.O.A.L of 2.230.

    Accurate Arms powder shows almost exactly one grain more for service loads over bolt action 223 Remington loads for all bullet weights and all of their powders.
