When it comes to your success as a hunter, what you’re shooting plays a major role. Ammo comes in quite a few calibers and grains, and each of those factors can make a big difference in shooting accurately and taking down the game you’re hunting in one shot.

In recent years, the trend has been for bigger bullets. Although there are valid arguments for using bigger bullets when you hunt, that doesn’t mean those are always the best choice. Here’s what you need to know about the latest bullets on the market and how you can choose the right ammo to fit your needs.

Big Bullets Have Become a Big Deal

2017 has seen the release of quite a few new hunting rounds, and several of them are on the large side. In 2016, Norma released a 6.5 Creedmoor hunting round weighing 130 grain and clocking in at 2,789 feet per second (FPS). It outdid itself this year with a match-grade round that also weighs 130 grain while traveling at 2,851 FPS. The 6.5 Creedmoor is intended for long-range accuracy and stopping power, as it remains effective past 1,200 yards.

Federal Premium introduced its Edge TLR, and it’s available in several calibers, including .300 Win Mag, which weighs 200 grain. The .300 Win Mag rounds can be effective at up to 1,500 yards, depending on conditions, and are able to take down medium to large game at that range.

Winchester also has different calibers available in its aptly named Big Game Long Range ammo, including the 6.5 Creedmoor weighing 142 grain and .300 Win Mag weighing 190 grain.

The fascination with these larger rounds is interesting when you look at how military preferences have changed over the years. In the late 19th and early 20th century, the U.S. military always wanted the biggest, baddest cartridges. There was the .30/40 used by the Army, and then the enormous .45/70.

The Spanish-American War changed how the U.S. military saw ammunition. During the war, Spanish troops had success with their lighter, faster rounds. This resulted in the creation of the .30/06, which used smaller bullets and shot them much faster. It became popular with the military, and later on, it became one of the most popular choices for hunters.
