Really liking using ARComp powder with 123gr bullets in my 6.5 Grendel. Next up will be using 8208 for some 100gr screamers.
But today the bullets and rifle worked together well for me. There were a couple other groups that were all under an inch in size scattered across the different areas of the target. So I decided to see what I could do if I slowed down for a good group.
Overall Size - .645 " (used the cardboard from behind the target paper)
Caliber - .264"
Group CtC - .381"
Top part has three impacts. One of the lower shots was the first shot with a rested bore. The other lower shot was a bit of a pull; either way plenty to be happy with this group after the rocky start I had with this rifle.
And some load data since this is the reloading area...
