I did a little search on the web and it wasn't conclusive... Does anyone know where we can get Mil-spec ammo for an AR15 in Canada???:confused:

thanks!
 
Their is a difference in between 5.56mm NATO and .223 Rem. I would check your barrel to see which one you have. It is not advisable to shoot 5.56 out of a .223 barrel as the dimensions/tolerances are different enough that they can lead to problems with overpresssure in the chamber. If your gun is .223 then bulk Winchester white box would probably be the cheapest. I don't know of a source of surplus 5.56.

Re-read your article. You've got it backwards. The only difference is the 5.56 spec chamber is more generous in the neck area and has the throat cut deeper than .223 Rem. You can fire .223 Rem in a 5.56 spec chamber all day long without problems. Compared to a .223 spec chamber, your velocity and accuracy might be reduced in the military chamber, but the pressure will be quite safe.

If you were to find true nato pressure 5.56 ammo, and chamber it in a .223 Rem chamber, there is a possible problem. The Nato loading was pressure tested using a chamber with a more open throat, so the bullet is free to move quickly. That same load in a .223 Rem chamber will have the bullet stopped by the rifling earlier, and the pressure will likely be greater. As the neck area is also tighter in the .223 Rem chamber, there is less room to expand and reduce the high pressure.

In truth, most of the 5.56 ammo sold commercially is simply badge engineered .223 Rem.

You're right Canuck. I read and re-read the Oracle's ammo thing long before asking for mil-spec ammo. I have the 5.56mm chamber, so I'm ok for .223 and 5.56mm. I really would like to shoot mil-spec ammo, but it seems that it is as rare as...!

You can always load your own. I don't recommend getting too adventurous, but they are your eyes and fingers.

You can always use a chronograph and your dial calipers to check pressure.

Now where would you get the ss-109 bullets?:rolleyes:

The only stuff that I could come up with that is even Commercially close is Winchester White box USA 223

Ya that's what I've heard and that's what I'm getting. But a U.S. friend told me "People down here use winchester white box just for plinking around. If you want something for defense try and get hornady tap ammo. supposedly it is what the police use."

It's not fair... THEY always have the good stuff... Canada is not a good place for gun stuff...
 
.223 vs. 5.56mm Similarites And Differences.
-Have the same exterior dimensions and lenght
-5.56mm is loaded to produce higher velocity and chamber pressures.
-5.56mm has thicker case walls for extra strength needed to handle higher pressure.
-The difference comes in the chambering of the rifle, and the difference is in "Leade" aka throat which is the portion of the barrel directly in front of the chamber where the rifling has been removed to allow room for the seated bullet. 5.56mm chamber throat is typically .162" - in .223 chamber it's usually .085". About half of a 5.56mm
-Firing .223 though a 5.56mm rifle you will get a slight loss in velocity.
-However if you shoot a 5.56mm cartridge though a rifle chambered for .223 it is VERY UNSAFE TO DO SO. I have seen a Ruger Mini-14 blow up nicely do to the fact someone was firing 5.56mm out of it.

If you have actually witnessed a blow-up, you are the first one I have met.
This subject shows up often, yet no-one seems to have actually seen it happen.
Also, on one of the threads, someone stated that the Ruger Mini14 is in fact chambered for the 5.56mm
 
AE I find is better than Winchester "white box". The fact that AE is cleaner and cheaper goes along way. I believe the last batches of AE as well are US military overruns as I have seen it with the nato stampings as well at the 55gr with military manufacture and year code.

Just my 2 cents....

Yet another thread of someone looking for milsurp 5.56mm and I feel embarassed that a country as great as Canada and there's NONE.......

And another thing..... There likely is no such thing as "milsurp" 5.56mm
What you're looking for is "cheap ammo"
All the .223/5.56mm found in stores came directly from a distributor who in turn got it from the manufacturer thru normal channels....
It's all commercial. Produced for retail sales....
My definition of military surplus is just that... #### that was once owned by some gov't and now has somehow found its way to the market....
...But that doesn't sound as cool as "milsurp" I guess
;)

When you think of it, true surplus 5.56 should not be hitting our markets. Surplus ought to be the result of a switch in calibers, lost lot numbers, or poor rotation methods.

I don't know of any western nations moving away from the 5.56, and we don't seem to loose track of ammo as much anymore.

There's a difference between "Milsurp" and "milspec". I don't care if the ammo is 100% commercial... but as long as it is loaded to 5.56mm pressure!

Up 'till now if I resume your suggestions, the "best" things to get in our circumstances are Winchester's white box USA and American Eagle.

We should put our ressources together and build a list of MIL-SPEC (not necesseraly milsurp) ammo suppliers. I'm sure many of us would profit such a list.

Or better, let's all chip in and buy a ####load of milspec ammo from an american dealer. (a really big ammount, so he couldn't refuse) Well, It's utopic...:rolleyes:
