I have them in 7mm 150gr. Last weekend i shot ground squirrels with them out to 525 yards. My scope is a leupold 4.5x14 cds. I have a 300 yard zero, 3" high at 100 yards.
At 6 additional clicks 1.5 moa, i hit dead on at 400. 11 total clicks (5more) was dead on at 500. This would hold the bcs as true for 3450fps. I was at 1000 ft elevation
I was shooting a rem700 in 7stw with 80 gr of 7828. 26" barrel..
