Will I be able to shoot 762 with my 308 JP supermatch barrel and young manufacturing BCG? It's my first AR build and have been getting mixed answers

Yup. Been doing it for years as have many others.
Of course there will be someone here who will post otherwise and say you are going to blow yourself up.
Technically, they are not the same. HOWEVER, practically speaking, they are interchangeable.
Some rifles eat both, others prefer one or the other. My Rem700 in .308win doesnt like some 7.62 NATO. It feeds fine but a little stickier to extract. I think it really depends on how tight your chamber is, the headspace, the OAL, and loading of the ammo you use.
All my autoloaders cant tell the difference.
There are probably thousands of threads online about this topic.Last edited by Tere_Hanges; 12-29-2016, 11:41 AM.CRPA and NRA member.

Yes no problem.A 30cal will reach out and touch them. A 50cal will kick their butt.

5.56 NATO is higher pressure than .223 R.E.M.
The opposite is true in 30 cal
7.62 NATO has lower pressure than commercial .308
7.62 has a bit longer throat...

not irrelevant..
if knowing the relationship difference between the two most common .mil cartridges confuses anyone, then they need to pay closer attention..
although in almost all cases, both related cartridges are universally interchangeable, it is still wise to know the difference..
selecting proper, safe ammunition for vintage or light duty sporting arms, selecting ammunition that wears better on the barrel, troubleshooting failures or malfunctions, etc. are all good reasons to know the difference..
and I think it's also important to note the difference between which .mil cartridge is more powerful than its commercial counterpart and vice versa, since they are different in that regard..I started out with nothing - and I still have most of itComment

only use what is stamped on the barrelComment

Depends, try and confirm if it works. 7.62 Nato cases are slightly longer, thou not much. Using 308 win in a GI 7.62Nato barrel that is on the longer end of the headspace measure can stretch 308 win brass too much, and separate the case head. This has been my experience with GI M14 barrels. In general 7.62Nato and 308 win should be close enough.The only thing that is worse than an idiot, is someone who argues with one.Comment

it does in this case..
some folks may easily make the assumption that all .mil cartridges are higher pressure, bigger, longer, etc. than their commercial counterparts - which is not true..
case in point, op states he's already received mixed answers..
knowing this relationship is not a rule across the board is not only important but very simple to commit to memory for years of future reference..
and either way, what the hell is the problem with adding a little more information to help someone understand?!
geez guys, is it a full moon or something?

Still not relevant. Why someone would make the same assumptions about 7.62/.308 as .223/5.56 is just dumb. Usually they do this because someone brings up the two as similar situations when they have nothing to do with each other, other than the fact that they are both a type of ammunition which can be said for all ammunition. A good rule of thumb is to not make any assumptions about ammo and firearms in general. Ask specific questions and get specific answers
BTW, OP never said anything about .223/5.56.Last edited by Tere_Hanges; 12-29-2016, 1:17 PM.CRPA and NRA member.
