Well I'm not a reloader just yet, so factory ammo is all I've got to compare. For me the FN recommended Federal GMM 168 SMK has been the best at .405 MOA at 100 yards. The heavier 175's have been close, sub 1 MOA, usually right around a half. I suspect the 175's will out perform the 168 from 400-1000 yards, but the 168s haven't disappointed all the way out to 1000.
I really want to try the buffalo bore sniper ammo. Anyone have any data on it through an FNAR?

In order of preferance:
Note: I've yet to chronograph any of these loads. They are very close to each other in terms of group size. The first load seems to be the most consistant. It shoots extremely well in all conditions I've encountered at the range.
168gr. Horn. BTHP
46.0 gr. BL-C(2)
BR-2 primer
Lapua brass
COL 2.800
168gr. Horn. BTHP
42.0 gr. H4895
BR-2 primer
Lapua brass
COL 2.800
168gr. SMK
44.0 gr. IMR4064
BR-2 primer
Lapua brass
COL 2.800
I am working up a load for my FNAR. I do not have any final results yet, but so far am shooting the following:
168 gr. Sierra HPBT
Varget 43.8 and 44.3 grns - I've tried many others, gun seems to like these the best.
Lapua Brass
Winchester primers.
I'm trying to get the best velocity for my barrel. I have the heavy barrel, and have had some good groups, but need to hit the range when the wind is NOT blowing for final results. I'll keep you posted.
42 grns IMR 4064
Nosler 168 HPBT
LC brass
I edited because I put the wrong bullet name in the post
Just did some new loads....
Hodgdon H4895 42.7 grs.
Sierra MatchKing 175 grs.
S&B brass 2.005 length
Wolf primers
OAL 2.804
Very accurate, 3 in less the the size of a dime @ 100 yds and windy.
This will be my new favorite load for the FNAR.
I had to re-zero the scope so those two on top was part of the scoping zeroing. The group was 3 when the wind slowed way down.

Looks like a keeper. I don't reload, but I would be happy with that from any ammo maker. I am warming up to the idea of the 3 shot group. At least I know my first 3 will be exactly where they need to be.
My most accurate load is
Lapua d46 170gr
vihtavuori N135 38gr
coal 71,00mm
Federal match
Une ole 100mt.
Is Any other testing 748 winchester 180gr bullets?
My target load is:
Sierra Palma 155 grain hpbt
44.5 grains Varget
Winchester Brass
CCI primers
C.O.L. 2.800
It produces groups around .8" without much trouble, I'm sure I could tighten it up a bit with some more time behind the rifle and I need to play with C.O.L.s, but all in all I'm very pleased with it's accuracy.
My hunting load is almost exactly the same data except for switching the bullet out with Nosler ballistic tip Spitzer in 150 grain. Same power, charge, brass, primer, and accuracy is equally as good.
Gentlemen, I encourage you to do some chamber measuring. I was shocked to see the max case length and C.O.L. On mine, I can get away with brass up to 2.055 long and with the Nosler Custom Comps 168gr my COL length is 2.862. I'm awaiting my bullet comparator so I can get my exact specs from heal to ogive.
There is a few sticky threads over at snipershide that show how to measure this stuff, its easy and the tools needed are pretty cheap, about $30
