Went to the range today the sierras actually shot a lite bit better than the SST. The SST was about 50 feet per second faster but the sierra was shooting a .486 inch group and a .55 inch group. Also the sierras had a standard deviation of only 7 fps! Average speed on the 30-06 with the 165 grain sierras was 2813. The high speed was 2817. And the low speed was 2806. And three of the five chronographed 2817.
Also shot them at a gong at 300 yards today and all three bullets on the gong you could cover with a fifty cent piece.
