Do you guys run FA or SA carriers? Standard or heavier buffers? The new 300BLK comes with an FA carrier and H2 buffer (which I am somewhat surprised about).

The batch with 7.7 grains of AA#9 under my 175s and standard buffer cycled well this morning. I might bump it up a bit they chronoed around 950s-960s and was not happy with the 5 shot group at 100 yards. Following the 300BLK load testing today I swapped to my 18" SS, FA BCG, and H buffer and put another 70 rounds down range. I still can't get over the versatility of MRP.
