In my 700 VLS i am using a 55 grain Sierra GK Spt with 26.9 grains of varget and the other day i was able to produce a 3 shot .331 at 100 yards, .339 at 200 and just went out today and shot a .610 at 300! I have only shot 1 coyote with this bullet but it was a 289 yards shot and he didnt take a step.
