Went to the range yesterday even tho it was pretty windy out to sight in the Burris Prism 536 and test out some reloads with 844T powder.
This is a 30 round group at 100 yards from my S&W M&P AR15, Burris Prism 536. A Grip pod bi-pod was used no sand bags or rest.
Round fired was 40g Hornady Z-Max, PMC brass, 24g of 844T and Wolf SRM primers.
I don't know what the wind was whipping at but it was strong enough to blow my AR off the bench while still in it's case.
