Since I am new to the rifle scene, got a question(dont want to get the wrong ammo). I'm planning to buy a case from cheaper than dirt. They have this Winchester .223 but i dont know if there is a difference between the two since they are both .223. If there is not a difference, they why the price diff.
1. Winchester USA .223--3.99
2. Winchester USA .223(5.56)- 3.69
Can anybody help me out, tried calling but could not get through to customer service. Correct me if I'm wrong but isnt 5.56 the same as .223

Negative-they are NOT the same. 5.56mm is loaded beyond the SAAMI-spec'd .223. 5.56mm chambers have a longer leade than compared to .223's. Most mini's I believe have 5.56mm chambers. Now if the Winchester they advertise is Q3131A, mfg'd by IMI for Winchester, I would prefer to get that. Regular Winchester white box .223 tends to cause trouble for some AR's, but are ok for mini's.
The .223 Win white box stuff is normally found in 55 and 45 gr weights.

Mikr is correct. 223 Rem, and 5.56mm look the same, but the 5.56mm i.e. M193 is loaded to 60,000 cup, where as the 223 Rem is loaded to 50,000 cup. The mini can shoot either, as it has an A2 military chamber.

Q3131 is made in Independance, Mo. at the Federal Lake City Plant. The Q3131A made in Israeli. Both shoot about the same, and both come in the Winchester USA white box.

dont want to get the wrong ammo

The Winchester seems to shoot well in most mini's. My mini likes them. I would suguest getting a couple of boxes of each to see which your mini likes. If they shoot the same, go for quantity on the cheaper one. Each rifle is different, yours may or may not like winchester. Better to check it out before buying quantity.

Both Mikr and Cajungeo are right. I made a genralization that I shuold'nt have. The .223 and 5.56 are interchangeable in the military chambering (that the mini 14 utilizes) but not the other way around. Chamber pressures are too high when shooting 5.56mm in .223 chamberings. Thanks for the corection!

 

[Cop369]

So in other words, I can use the 5.56 in my mini-14 with no problem, correct? And what about its use in the AR-15

 

[mikr]

Mini's should be all right. AR's, provided they are stamped 5.56mm or "Wylde" on the upper should be just fine--beware .223 stamped uppers-or contact the mfg. for assurance.

Thats afirmative. You got a manual? If not click on the New Ruger site sticky above, select manual, and getcha one! There free. Check out the cover upper right, and Ammo page 8.

I won't comment on ar's, but its the same A-2 chamber.

The boys on the AR site are having fun with this question!

 

[Bear 1769]

Will the M885 round operate in the mini or is the chamber diffrent for this round and the rate of twist on the mini to slow?

 

[voruzon]

M855 should be fine with the 1:9 Mini twist - unless the weather is exceptionally cold or you are in a deep cave, both conditions raising the air pressure - and the round dimensions must be the same. It is only the even longer M856 61gr long range tracer that needs 1:7 twist under normal conditions.

[mikr]

You mean M855? It'll be just fine. Even in 1/10 out to 300M.

Whoa!! Wait a minute!! Sellier and Bellot are better known as Sellier and Kaboom!!!

At that price I would get our own Federal Lake City mfg. ammo from www.wholesalehunter.com

Too many rifles had problems and breakage and even their .45ACP ammo is problematic, I would testify to that....

S&B could be considered in the same boat as Olympic
you'd rather your enemy had them in their rifle
