?why not .223 Rem?

Sneaky pete here: Do you have an exceptinally huge ammount of 5.56x45 mil surplus ammo availiable to you-- well it WILL work in a .223Rem chamber also. In '72 I purchased a Colt SP-1 AR-15 .223Rem. I was in the Reserves and shot on our Bde. rifle team and was issued Mil Spec 55gr 5.56x45 (M-16)ammo for practice, which i shot out of my Colt SP-1. I still have some laying around the house. I don't use it because #1- it's not that accurate( velocity spred to wide), #2-I handload with moly B/T projectiles. NO I don't know of commercial bolt rifles chambered in 5.56X45--But there are tons of them in .223 Rem and remember to get a twist that will accomidate the projectile weight that you plan to use. Good luck. THANX--SNEAKY

5.56x45 is hotter than .223 rem. Rifles chambered in .223 rem SPECIFICALLY may have warnings about 556x45 ammo. The Remington 700 SPS and 700 VTR come in .223 as do the Savage 10/110FP's and 11/111FP's. There are others out there. I have heard VERY good things about the Remington 700 VTR in .223

9mm vs .45 ACP? The answer is .429

223 Vs 5.56x45

223 Rem Is The Same Round As 5.56 X45 Yes Nato Ammo Is Loaded Hotter But Not Off The Charts The Cases Are The Same Size All The Way . Weed Are You Trying To Say That The Rem 700 Is A Weeker Action Then A Ar 15 And That Natio Ammo Is So Much Hotter That You Cant Use It In A Bolt Gun. Back To The Question Most Us Gun Makers Use The Name Of The Round To Mark The Barel So That You Buy The Same Matching Ammo From Them Rem Does Not Make 5.56x45 Ammo They Make 223 Rem Ammo.

The reason I asked about a Bolt Action Chambered for 5.56mm is because of this article and others like it that I have run across on the net.

It makes since to me, based on the info supplied at the fulton site, to have a rifle chambered for 5.56 and a barrel twist rate of 1in 9" or 1 in 8" in order to take advantage of surplus, bulk ammo prices.

The primary difference between 5.56 NATO and 223 Remington is in the throating, which can affect pressures when longer NATO bullets get jammed into the rifling on shorter throated 223 Rem rifles, causing a high-pressure spike. Spec pressures on the two rounds are measured in different places, so it may look like they have different pressure specs, but for all intents they are the same. But there are many, many shooters who shoot 5.56 NATO military ammo out of their 223 rifles without problems of any kind.

Most if not all rifle manufacturers offer rifles chambered in 223 with the faster twist rates needed to stabilize the heavier bullets. I would recommend a Remington, Ruger, CZ, or other high-quality rifle, since you will be satisfied with its performance for a long time.

I'm happy as can be with the 1/2MOA of my Ruger 77 Mk II in .223. I've done just fine on prairie dogs to 300 yards.

If the issue of the throat bothers anybody, just remember that God invented reamers that will make any .223 have the same throat length as a milspec 5.56.

Get It!

Get The 700SPS Varmint I. Got the rifle at Dick's Sporting Goods (its $550 there, but i got mine on sale for $500). Its a SPS and green, But doesnt have the stupid triangle barrel. Its In .223, and it shoots great. with a week's practice, you can hit a Quarter at 100 Meters. it has low recoil, a smooth action, and is crazy accurate.

Most newer bolt action rifles are designed to chamber both rounds. Contact the manufacturer of the rife(s) you’re considering to make sure. I know the CZ 527 chambers both w/o a problem.

I wouldn't worry too much about it so long as you're getting a relatively new gun. Most newer models come throated for the heavier bullets and should therefore be fine with 5.56 Nato ammo. Also, most bolt guns in this caliber are based on a Mauser type action which is very strong.
