i loaded 2.260 which is 035 off the lands. Next round going down progressively by .005 didn't care for what I got with them. Kinda disappointed since the 120 Match did so well. Best was around .8 or so.

Depends on your throat and what your barrel wants.
It is typically easier for any cartridge to start off with a short OAL then get longer once you find your accuracy load.
Increasing your OAL slowly will usually (usually) drop pressures some till you start engaging the lands of the barrel.
Unfortunately only you can determine your throating length.

I don't have my log in front of me, but I do remember I needed to seat the FAR deeper then the Gold Dots I tested before them.

I started shooting them with the same Benchmark powder that shot well with the GD bullets. @ 27.3g I was rewarded with nice accuracy. I haven't had a chance to test anymore yet.

Sorry Photo Bucket is being PHOTOBUCKET and not working...

I ended up doing 50 rounds yesterday in incremental powder charges at 2.135 with a variance of +/- .005 we shall see how it goes

Those touch the lands at 2.16" in my barrel (SAAMI chamber).

My load that shoots better than I can hold out of my 18" Oden Works barrel AR is with the 120 Sierra Pro Hunter. Hornady case, CCI450, 28.5 Grs IMR 8208, COAL 2.260 and I use a medium Lee Factory Crimp Die crimp. It averages 2550 fps and sub 1/2 MOA when I don't mess it up. LOL

I just shot a batch of these and 8208 xbr. I loaded them to 2.24 and 2.260. Charges were from 27.6 up to 28.4. Best load was shown at 2.24 and 28.1.

So, loaded up 50 rounds and my best groups were with 28gr of h335 and were grouping around 1.5moa. Not bad for hunting ammo but the Hornady Black consistently gets me .8s and .9s.

Got this today was a little windy.
