I know with 5.56 chambered rifles you can shoot 5.56 and .223 but not the other way around (unless .223 Wylde). I know .308 and 7.62 are interchangeable but is there any benefit to chambering for a specific one to be able to shoot both?
Gunsmithing .308 or 7.62x51 Chambering

.308 chamber will let you shoot both.
Hot .308 loads technically exceed pressure specifications for 7.62x51 chambers.

yes- as Wirgman said- 223/308 are backwards
5.56 has higher pressure and a longer throat.
308 has higher pressures than it's NATO spec 7.62x51.
So.. go with a 308 barrel... ok to shoot both....
and most will say, they have never ever heard of a KB from shooting 5.56 ammo in a 223 firearm

I should have probably just said regular 308 as I am not an expert to advice specifically on a 308 "match" chamber. What I can say though, is that as long as the reamer is good and not so worn, if the Smith cutting your chamber does it right, it will more than likely not shoot bad.
