We can chamber in .223 Wylde, this is a match grade chamber capable of firing both .223 and 5.56mm ammunition.
The chamber has increased leade that allows 5.56mm ammunition to be chambered and fired safely without increased pressure associated with firing it in a short leade .223 chamber.
I have not seen such a thing written before when looking at .223 straight pulls, do you think it is worth having done and what, other than the already mentioned, benefits are there?

PS he also has the reamers for 300BLK should anyone have been interested.
Yes the 5.56 surplus gear is a little more pokey than the normal.223 i dont put surplus through my remmy,but do through my ar as its desigend for it,i think youll find the 2 cartridges arent exactly the same, i does get technical.........
When someone says "it's not about the money" you know what? it probably is all about money!
With the appearance of full metal jacket military 5.56 ammunition on the commercial Market, it has come to the attention of the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) that the use of military 5.56mm ammunition in sporting rifles chambered for Caliber .223 Remington cartridges can lead to higher-than-normal chamber pressures and possible hazards for the firearm, its user and bystanders.
Tests have confirmed that chamber pressures in a sporting rifle may be significantly higher in the same gun when using military 5.56mm ammunition rather than commercially loaded Caliber .223 Remington cartridges, according to SAAMI.
SAAMI points out that chambers for military rifles have a different throat configuration than chambers for sporting firearms which, together with the full metal jacket of the military projectile, may account for the higher pressures which result when military ammunition is fired in a sporting chamber.
SAAMI recommends that a firearm be fired only with the cartridge for which it is specifically chambered by the manufacturer.
Having a Wylde chamber can't hurt, if you want to fire both Milsurp and Factory ammo and not have any potential worries about the pressure difference.

YUP,
More a case of probs arising if not and feeding 5.56 through a 223. Higher pressures in tighter chambers isn't a good receipe.
We may not be able to get our hands on 5.56 at present but boy is there going to be mountains of surplus available, once we get out of the farce that is Afghan (hopefully )
My AR has a Wylde chamber I have never had a primary extraction problem using surplus ammunition (and I also shoot both .223 ), I have seen rifles with standard chambers being attacked with boots and hammers in the past to extract a tight case
What is a Sapper? This versatile genius condenses the whole system of military engineering and all that is useful and practical. He is a man of all work of the Army and the public ready to do anything or go anywhere, in short, he is a Sapper.
