These are my first loads for 6.5 Grendel, and overall I am pretty happy with them.  Could not get the chrono to stand still again, thanks to the wind.  It seems like every group had a flier, which hurt my numbers, but I still think it'll do.

The setup for the day: 20140301_090434[1].jpg 
I used 8208XBR and the OAL was 2.250 for all loads, as I'll be playing with the length next.  Here are the groups:

Needless to say, I am going to stick with the 28.0 or maybe push load to max and see where that leads me.

That is a Satern cut-rifled 18".  The only issue I have had with it were with my loads, and I failed to trim 3 pieces of brass.  When I measured them, they were about .22mm long and didn't go completely into battery.  There were marks on the neck but not on the bullet.  

I am still battling a feeding issue with my 10 round AA mags.  I just can't get them to reliably pick up the cartridges unless I am applying upward pressure to the bottom of the mag, even when manually cycling.  Honestly at a loss.

Here is a group with factory ammo from PF (123 SST).  The two shots that aren't measured were done after shooting that group.  The last time I used these cartridges, I got .5 MOA @ 200 yards during a stout wind.   Screenshot_2014-03-03-11-38-28[1].png
