I plan on running a bunch of ammo through mine this weekend.
I have IVI, Hertenburger, Santa Barbara, various commercial and hand loads to try. Also an SR match I may use it in as well (not really looking forward to the rundown...)
Might post some photos of my findings if I've got time.
Edited to add:
I slapped a Nightforce 2.5x10 NXS and a PWS break on mine and had it out for a bit more fun.
All groups shot were from prone using a bagged front rest for support.
First group was a confirmation of my earlier use of Hertenburger surplus. Results were about on par for this stuff. Very underwhelming.
Next up is the excellent brass-in-waiting of a batch of 70s IVI.
After this I settled on some handloads I had made up last year to test in my TRG 22. The night before I had to crunch them down .05" so they'd fit in the Pmags... Brass is virgin Lapua, fed 210m primers and either AA2520 or Varget with 168gr. SMKs
AA2520:

Conclusions:
No real suprises - Surplus ammo is that for a reason. I'll happily run this stuff through my M14, but this LMT deserves much better.
Since I can't afford to run factory match ammo like the RUAG or GMM, handloading is my only real (and in fact best) option. I'd recommend prospective buyers of these guns to consider that before heading out to make a purchase.
I need to start working up handloads for this rifle specifically - not using handload hand-me-downs from my boltguns - something that is on par with my experience of loading for AR15s.
This thing chucked the brass about 4 ft to the 2 o'clock position, so instead of hunting for brand new Lapua brass like a madman, I'll stick to winchester brass.
The PWS brake on the AR15 isn't bad, but on this thing, a bit of a beast. I'm hoping to try out the Battlecomp offerings if and when they are available up here (any vendors working on this btw?).
Next up is some tailored handloads, maybe a bit more glass and some shooting from the 800m mound...stay tuned
