Not familiar with the Larue issue, but with my 7" .30 cal Thunderbeast I had to dial the gas way back with my load.
I was running a standard 3 oz carbine buffer, but have since changed the steel weights out for tungsten ones to bring the buffer up to H2 weight. This was done because I had a couple of FTF's whereby the round stripped off the mag and chambered, but not fully into battery. I am hoping the added mass to the buffer will generate more momentum. I am curious to see how much, if any, I will need to open the gas system back up.
Actually, I hope it is to full gas or nearly so which will make the swap from suppressed to non-suppressed fire less involved. If the rain ever stops, I will be heading to the range to launch a few 6.5's and to do some more subsonic development with my 8" 300 AAC.
