I'm on my 3rd barrel (all 26") in 6 Creed. The previous 2 I ran H4350 in necked down Prime brass with 110SMKs and CCI BR2s. One barrel liked 42.3gr and the other liked 42.2. The 7.5 twist got 3050fps and the 8tw 3080. I decided to try H4831SC since it's sometimes a pain in the ass to source 8lbs jugs of H4350. So far I'm getting good accuracy, consistent .5 or sub-.5moa 5 rd groups at 200 yards. The problem is the ES is terrible, like 50fps. In both previous barrels I was getting an ES of about 20fps. This is all using the same reloading methods, obviously. I have a new AD FX-120/auto-throw/auto-trickler coming which I figure will bring the numbers down but not that much. Maybe a change in primers? Try some Fed 210M? Is there something else I'm missing? I haven't tried playing with seating depth yet, I'm at 0.020 off the lands right now. Any help much appreciated!
