I'm still working up loads for mine. Today I shot and fire formed brass using lapua cases fed 210m primers and 4064 fire forming 42.4 grns looked promising. I'll have go back and tweak the fire formed cases now. I have post showing my loads and chrono data in another thread here.

Kinda amazing to find that most precision 308 loads are very similar, no matter what rifle.
This is why I enjoy shooting 308's, its very forgiving.
I am now trying to find a good load for a 185g Berger Juggernaut with my AIAE MKIII, anyone have any loads for this?
I got Lapua brass, Win brass, 210, and 210m primers, Varget and 4064.

What barrel and twist do you have...I have a factory 1-12 and 175's are the max I'm gonna put through it...
 
Hah! I have the 'exact' rig that you have: 20" bbl with muzzle brake in DE. I threw some Multi-Cam Viper skins on it since - I really like the pistol grip! Mine loves just what was mentioned: 43.0gr of Varget under a 175gr SMK powered by a CCI BR-4 primer in Lapua Palma Win308 brass (small primer pocket). Velocity is in the 2430-2445fps range as per chrono and long-range validation and the SD is usually around 10fps for a 10-round string. It ain't exactly a fire-breather, but it sure is accurate - 0.25-0.50MOA consistently if I do my part. On the upside, your brass will last a LONG time. On my 14th reloading. I try to anneal it every 4-5 firings and have only had a few necks crack at this point. I absolutely love my AIAE Mark III! Too bad they're doing away with them :( I'll definitely get another AI! I'm done trying to massage Rem 700's,... Oh, I've had Rem 700's that can really shoot, but they aren't nearly as smooth and trouble-free as an AI - it just runs! Enjoy!

I love my AI. I am keeping my 700, but will be sending it to Gap for some Magic Dust and turn it into this new 22 Creedmore I'm hearing of.
