New to the .308 AR

[JGshooter]

Hey there,  I have owned an M1a1 SOCOM,, and now in the market for an AR variation .308. I'm thinking the Rockriver arms operator, or Bushmaster ORC carbine. I reload, using the 168 gr sierra HPBT and varget powder, which I have used for my SOCOM, is there any changes in reloading data that I need to take into consideration, going to an AR .308?

Thanks for joining JGshooter. Keep in mind the Bushmaster is DPMS LR-308, in fact the Freedom Group is shuttering Bushmaster. That said there seems to be awesome deals around on the Bushy.

How do you like the  SOCOM? Thats on my list.

If you're looking at cross-breeding with aftermarket parts, I'd advise not going with the RRA gun.  There's so many little things that are different from the two "basic" types that you'll have a hard time finding aftermarket support for it.  My $0.02. 

Welcome aboard, by the way...  ;D

It can go right on my RR Ar-15 Lower

Very nice but pricy..I bought a 450 busmaster upper for 499.00 on sale, and put it on a RRA lower with a 2 stage trigger, I picked up new at a gun show for $250. ammo not too expensive to reload, and makes a great hog gun...

Well lets just say I could ALMOST have a 6.8 and a 458 RRA upper assemblies for what I got in just my lower DPMS.
