I think I need to get the 220gr version. I just started playing with the 200gr version last weekend. I have not done any terminal testing with it yet just getting the velocity dialed in. My first batch did not go well. I get the velocity I wanted but then it would not cycling my AR and my AR has yet to see a load, super or sub, it would not cycle. I have a 16-inch barrel, pistol length gas system, with an AAC SDN-6 can.
My first attempt:
Bullet: 200gr Maker
Primer: Win Small Rifle
2.105 inch OAL
Powder: IMR 4227
Charge: 9.9 gr
Avg Vel (5-shot): 1104 fps
Charge: 9.6 gr
Avg Vel (5-shot): 1053 fps
Charge: 9.3 gr
Avg Vel (5-shot): 1024 fps
9.9 grs ran fine but it was super sonic. Both the 9.6 and 9.3 gr has a few short stroked that ejected but failed to get back far enough to strip the next round and did not lock back on the final round.
My next attempt it going to be to switch to Accurate 1680 and see if that will cycle.
