Picked up a new Browning X-Bolt in 6.5 Creedmoor a few weeks ago. Load development went well. 140 ELD Match bullets, Lapua cases, CCI 450 primers and H-4350 powder.
I have been using the powder charge I settled on and adjusting seating depth to tune the load. Last range visit I had one depth that shot exceptionally well so I Loaded 50 more of them for further testing. I shot four groups of five shots tonight while recording velocities with my Lab Radar. All four groups look very similar in shape to this one. All four groups measured less than .35 MOA. This one just happens to be the best of the four. I am quite happy with this for a factory gun with no modifications other than lightening the trigger. Groups are measured from outside the bullet holes on the edge of the black carbon markings left by the bullet then bullet diameter subtracted from that measurement for my center to center group size.
Across all twenty shots velocity was very consistent.
AVG: 2778 fps
ES: 9 fps
SD: 3.7 fps
Today it was 32 F on the range. Last week when I originally tested this load it was 60 F. My average velocity today was only 8 fps slower than it was last week for the same number of shots. Like I said, very happy with this Browning rifle. I bought this rifle to hunt with, but maybe I will shoot a few PRS matches with it next year.
