My question is will using 556 brass in my 223 be ok or will it cause issues?
What are your thoughts?
Is it pretty much one and the same?

Ive used it for years without issue....I sorted headstamps and threw out one type as it seemed to have been subjected to hotter pressures(cant recall why I thought that) and had to twirl the deburring tool on mouth of primer pockets to remove crimp...I do use a mildish load so the old warning to back off powder a little as older milserp brass was thicker was taken heed of... thee days because Im at mild load level anyway I take little notice of what brass Im using in the wee rifle,it all groups within inch anyway no matter what rifle is fed LOL.
Thanks MD, I read online where 5.56 brass can cause dangerous pressure and the thicker cases are smaller so if loading heavy projectiles with hot loads it can be dangerous.
so dont load the 3 test loads so hot...like ANY change in components you are SUPPOSED TO drop down and work back up..... Ive always thought,well if its slightly smaller case,I will be getting higher pressure/velocity anyway so never bothered to load hotter..
for 20 years my go to load has been 24.5grns of AR2206h behind a 50-55grn projectile....... have a look at the loads fellas are using with heavies and you will ALSO see that same charge weight......strange as it may seem
also if you compare .222 and .223 load data the smaller case will have higher velocity with same powder charge......again strange but true.
Thanks MD, now I have my load sorted Im just not sure I can be bothered working up a load again.
Lazy I know.
go on..load 3 dropping powder by half a grain and shoot them and see......
Greetings All,
Weighing the cases or a sample of them will allow you to group the similar ones together. I have done quite a bit of this so will share my findings tomorrow.
GPM.
You might find this quite helpful. https://www.youtube.com/watch?v=VCS4fXFmCyA
Bought a weighed lot off Gun works ADI yes had to remove crimp primer pockets. Not a maximuim type of reloader I find a node back a bit that gives the accuracy I'm after. Loaded that brass heaps of times and it's been awesome. Don't get carried away with pressures and verlosity.
Someone who has reloaded the Belmont ADI brass can correct me if I'm wrong, but I would assume the Belmont Black brass shouldn't need any removal of old primer pocket crimps. I'm assuming Belmont would have already had to do that in-house to prime and reload the once fired brass? Someone on here will know the answer though...
The small amount of adi I've reloaded about 300 all had crimped primers was made for hunting and fishing by BelmontQuote:

Greetings All,
Relentless scrounging has resulted in a large supply of once fired .223 brass. Weighing the brass I found most of it fell into two groups one averaging 94 grains and the other 97 grains. This includes the fired primer. WCC and LC military brass also fell into these two groups. FC brass was a lot lighter at 89 grains and continental brass a lot heavier with Lapua, Norma and S&B at about 105 grains. My cases are sorted into batches with the same head stamp and those batches averaging 94 grains go in the T3 and the 97 grain ones go in the M700. The heavier cases will give significantly higher velocity and pressure so sorting is essential. Two loads are used. 55 grain projectiles with 25.5 grains of AR2206H and 69 grain SMK with 25 grains of AR2206H. These chronograph 3,150 and 2,960 respectively in the T3. Neither load is max but is a full case with mild compression. A switch to BM 8208 is being considered. A small sight adjustment is needed when switching loads in the T3. Cases are FL sized using CH dies and competition shell holders to give minimal shoulder bump and annealed every other firing. I have not found any need for a small base die in any of the 3 .223 rifles that I loaded for, even when using pick up military brass.

As a matter of curiosity, why do you guys go to that level of effort to collect random brass when Lapua .223 brass is relatively cheap and very consistent/easy to reload with?
Genuine question.
I don't think there are any 223 Lapua brass new for sale anywhere at the moment.Quote:

The Lapua brass, while excellent, is heavy and would have a grain or so less capacity than the US brass (and ADI from my limited measurements). Weather permitting I will do my first F class shoot on Saturday and have done a careful sight in at 200 metres so I can dial up to 300 yards on the day. Accuracy has been excellent, close to 0.5 MoA from a T3 Lite. The load is the 69 grain SMK ahead of 25 grains of AR2206H mentioned above. The case, LC83 picked up on the Roy's Hill range in the 1990's usually in neat piles so not as random as it could be. If I find F class to my liking a new or improved rifle may be in the future. I might need some Lapua cases for that. Those of us that grew up in the 1950's and 1960's will remember a very different NZ. Import restrictions meant much of the stuff we take for granted today simply was not available. We learnt quickly to make do with what we had, a habit that is hard to shake for most of us.

Absolutely fair enough. If it makes you happy, then that is the best reason going.Quote:
