The Best Caliber for Your Hunting Needs

From your best friend to expert marksmen, everyone has their own opinion as to which caliber makes the perfect hunting round. However, the reality is that there is no one size fits all when it comes to hunting. Factors like the size of the animal being hunted, the distance the round needs to cover, and the velocity of the round all need to be taken into consideration before deciding which round is perfect for you. With that said,30 caliber rounds are the most widely used hunting rounds North American big game hunting. There are many different rounds within the .30 caliber group and each one serves a slightly different purpose than the next. There are two extremely common .30 caliber rounds that are very effective in big game hunting.

Winchester .308

Ideal for ranges up to 250-300yd., the Winchester .308 is widely used by hunters when taking on whitetail deer or moose. A hunting rifle that shoots a Win. .308 will usually weigh about 8lb. This is fairly easy to carry without getting tired. Your typical Win. .308 round fired out of a rifle of this weight generates a little less than 20ft./lb. of free recoil energy, so it’s safe to say that you won’t have to worry about putting your shoulder out of commission after firing this round. The penetration is also good in most Win. .308 rounds. Penetrating 20in. into the target is no special feat for this round. However, outside of the 300yd. range, this round does start to lose its effectiveness, so you’re going to need another round for those longer shots.

.300 Winchester Magnum

Enter the .300 Winchester Magnum. At 500yd. a 190-grain .300 Win. Mag. has a little over half of the wind-drift as the Win. .308 does. It also retains its velocity better than the .308 at 500yd. The 190-grain .300 Win. Mag. maintains a velocity of 2,221fps. at this distance, where as the Win. .308 only maintains a velocity of 1,786fps. Obviously, this translates to more energy with the .300 Win. Mag. upon impact. At 800yd. the gap between the two rounds’ performance shows roughly the same picture. The drop for the same .300 Win. Mag. round is still just above half that of the Win. .308. The .300 Win. Mag. Now has a retained velocity of 1,860fps., which is considerably more than the Win. .308’s 1,375fps. This means that the .300 Win. Mag. is still effective to cleanly take down smaller moose at 800yd., where as the Win. .308 cannot maintain a velocity high enough to effectively expand the bullet upon impact. Just know that the .300 Win. Mag. comes with a little more kick than the Win. .308.

Though there are many different rounds to consider, these are two of the most common rounds used in North American big game hunting. The Winchester .308 is an effective medium-range round when taking on big game in North America, but you would want to upgrade to the longer, more powerful .300 Winchester Magnum when taking longer-range shots. Again, there is no one size fits all, but this should give you an idea of the different factors to take into consideration when selecting your perfect hunting round.
