I don't know if this is off topic but I was wondering which is better for an AR-15 that can handle NATO rounds, .223 or 5.56?
They make 5.56 hollowpointsI was asking because I had heard somewhere that firing the .223 round would be more accurate than the NATO round. Plus, I believe that the NATO round is always FMJ while the .223 can be either FMJ or JHP.
For CQC training, I agree. I dont see any difference in accuracy. As far as long distance shooting goes, I only shot 5.56. Not for any accuracy reasons, its just worked out that way. I got enough long distance shooting in the army.They make 5.56 hollowpoints
Someone correct me if I'm wrong but unless you're shooting a very long distance I don't think you'd notice any difference in accuracy using 5.56 over .223, the 5.56 is actually slightly more accurate than a .223 when fired from a 5.56 rifle, but I don't think it would be very noticeable, 223 is a lot easier to find, and often times cheaper. Either one works just fine for the range.
I guess my original post wasn't clear. My S&W MP-15, AR-15, is stamped for 5.56. Since I mentioned that it can *handle* NATO rounds I assumed that everyone would infer that it is designed for 5.56.This is fairly simple, BUT REALLY IMPORTANT!
If its stamped .223, ONLY shoot .223 out of it. Dont shoot 5.56 out of it. Heres the thing, a 5.56 shell will fit into your gun, assuming that its a .223. AND THATS BAD. If it didnt fit, you wouldnt have to ask.
But it will fit in your gun, and YOU SHOULD NOT SHOOT IT.
If the gun is stamped 5.56, you can shoot either 5.56, or .223.
If you gun is stamped with both .223, and 5.56, you can shoot either.
I just ordered 1000 rounds of 5.56 FMJ from bulkammo.com - they have bulk quantities of .223 also. I bought 100 rounds of .223 JHP from Cabelas a couple of weeks ago. Cabelas is rapidly restocking their shelves but they are still having difficulty getting .22 caliber ammo.Are they still making .223 and 5.56 ammo? Gosh, I haven't seen any in about 10 months.
