I shoot the 65gr SGK out of my AR and have superb accuracy, IMO. After much work I came up With this load: LC brass, CCI41 primer, 24.5gr of H335, 65gr SGK. Sub moa at 100yds prone with just a sandbag and a 3X scope. As most say, if you want to try this work up this load.
The sierra game king isn't a match bullet or a fmj, but I guess you can say in between!
Lock and load, the zombies (democrats) are coming (to take your guns)!
