Savage chambered for .223 can shoot 5.56 ?

[phil evans]

had a S&W Sport, ar15, barrel rollmarked 5.56/.223rem.
bought Savage model 10, precision carbine, barrel rollmarked .223 rem caliber.

can this precision carbine safely shoot 5.56 ammo?

I am just going to watch this from over here.

Is there room for 2 over there ?

OK, go to the Standard ammo & reloading section. They just put up a Sticky for ya.

Besides what I wrote in the sticky mentioned above, here is even more food for thought.

Savage makes .223 rifles in the following twist rates.

1 in 14
1 in 10
1 in 9
1 in 7

My Stevens 200 with a 26 inch heavy barrel and a 1 in 9 twist has a throat longer than a AR15 rifle, BUT I bet the 1 in 14 twist Savage rifles are short throated.

Meaning nothing is written in stone and your Savage might have a short throat which will cause high pressure when military 5.56 ammunition is fired.

Gauges are made for checking your throat length below.

Standard SAAMI .223 throat and military 5.56 throat below, the SAAMI chamber diagrams are "guideline dimension" and can be changed by the firearms manufacture. A long throated Weatherby rifle is an example.

surely did not intend to open a can of worms - hoped for a simple answer.
ALL - thank you very much for the helpful sticky and other resources that i will delve into:
while just shooting 200 unfired .223 lapua match brass
bought specific for the 1 in 9 twist carbine for a load develoment/accuracy ladder.

you could pull the bullets and work up til you get to the original load. if you make it that far before you start seeing pressure signs.

There is no simple answer to your question, military 5.56 firearms have a longer throat and the ammunition is loaded to a higher pressure. If your rifle has a standard short throat the higher pressure military ammunition can damage your rifle. You need to find out how long your throat is to answer your question, the answer from Savage is do not do it.

If you spend any time in AR15 forums you will see some AR15 rifles are having over pressure problems because some of these AR15 rifles do not have proper 5.56 chambers and throats. These rifle are blowing and popping primers and cases are getting stuck in the chamber from over pressure. In one case a Police Department was having these problems because the barrel manufacture sold the wrong barrels to the AR15 manufacture.

There is no simple answer, you need to check and see if you have a longer throat to be safe.
