 New to the forum and just purchased a DPMS LAR-308 AR-10, and was wondering if anyone on here has any experience with reloading 308's for the gas gun. I am leaning towards 165 accubonds since they perform well in my 300 RUM. Any help would be appreciated as i am new to reloading for the semi-auto's. Thanks again!

you dont really need to do anything different other than maybe add a crimp to the case mouth.

And maybe use small base dies, depending on your chamber.

I reload for an Armalite AR10.

One note, 308 gas guns are notoriously overgassed.  Shoot a few round through your LAR and look at the brass.  If there is a huge dent in the case, it is no longer suitable for reloading.  My AR10 launched brass about 30 feet and left a hell of a ding in the case (from hitting the brass deflector.)  I bought an adjustable gas block and now all is well, no dings, no overgas issues.

Use several 308 gas guns,Galil,H&K,Cetme,FN-LARs,AR10T,Eagle,M1A SS Match,DSA and the common element in all is primer pocket expansion, associated (mostly) with FL dies back to minimal dimension. This allows the firing pin to push the round fully forward until the pressure is high enough in the case to push it back fully seating the primer again. If your up to the brass rework, use LC brass (or other equal) with crimped primers and work with them for longer case life. Case neck tension is usually higher and some neck turning may be needed as well as reduction in charge as the thicker web usually results in less volume.

My LAR-308 would start to show high pressure signs with moderate loads.  Like punctured primers.  So I found that mild loads worked best.
