I built this rifle a while back and have been trying to get my technique down.  I really need to find some training, maybe some informational videos.   I've done some digging to find some videos around precision shooting auto rifles but don't find much.

Here are a couple groups using AAC 77gr factory ammo.  I haven't had a chance to hand load lately but will get back after that.

One of these days I'd like to get someone who can really shoot give it a try to see what it can do.

Not bad. My pseudo-MK12 with Rainier .223 Wylde loves 77-grain AAC.

Good shooting !

Have you tried the AAC 77gr with the Sierra 77gr ?  ( Another bargain priced AAC product )

And don't be surprised if the WOA barrel settles in even more after "X" amount of firing.

I'll work to get some new targets posted, but after a pile of rounds on this rifle and others I found that the problem was my shooting technique.
