Took advantage of the lack of wind and mild temps and lack of mirage Sunday here in TX and spent most of the day shooting out to 1000 yards. Starting at 400 yards I was shooting a friends rifle, verifying the drop chart (I use Ballistic, Brian Litz program) of a load I worked up for him. I typically do this from 400-800 yards. This will give you real world drops so you can tweak the inputs of your ballistic program to give the correct results. (BC,vel, scope height etc). The rifle I was shooting for my friend was a 338 EDGE. I had fired 2 shots at one of the targets getting the information I needed. Before I moved to 500 yards I thought I would give the new 14.5 5.56 tOBR a shot at 400. The small 5.56 holes weren't it going to mess up my results with the big 338. Shooting a handload of 77g Berger OTMs over 24.5g RL15 in Lapua cases and CCI BR4 primers at 2550 FPS.
The 14.5 tOBR is set up with a Leupold MK8 CQBSS. I dialed up 27 clicks (.1 mil clicks) and fired the first shot. The hit was just left of the POA and good elevation-wise. I then went ahead and shot 5 more rounds, quickly I must add, less than 30 seconds for all 5 shots. The resulting group surprised the heck out of me. All the Larue rifles I own, including one Field grade barreled tOBR shoot incredibly well. I have not spent much time with this particular rifle but apparently is is not an exception.
A quick measurement in the field damn impressive accuracy at 400 YARDS disregard the big red 338 holes.
After putting the calipers to it 1.22" or roughly just a bit over 1/4 MOA at 400 yards. Larue makes some pretty good equipment, I will say.
