I hunt with a sniper type very heavy m-14 with a douglas 1-10 twist 6 groove heavy barrel. I have been having great success on prairie dogs out to around 700 yards with a barnes coated 168. I just haven't seen any farther out is the only reason only 700 yds. I have gotten a couple of perfect kills on hogs out to about that distance too. The barnes works fine really but will the 175 smk at roughly the same velocity , 2600-2650 be any better a bullet maybe a little farther. I am getting great groups on a 1000 yard silhouette target already but would like a little less holdover if possible. I do the kentucky windage thing with my scope as it seems easier to me. I am just used to it I guess. The wind around here is bad enough to deal with and anything to help would sure be nice.
