Quick Answer
Both .308 and .30-06 can be effective for hunting Roosevelt Elk, but the .30-06 is generally preferred due to its higher ballistic coefficient and longer effective range.
Choosing the Right Rifle
When it comes to hunting Roosevelt Elk, a rifle with a flat trajectory is essential. Both .308 and .30-06 can deliver a flat shot, but the .30-06 has a slight edge due to its higher ballistic coefficient. The .30-06’s 180-grain bullet, for example, has a BC of 0.485, while a .308 165-grain bullet has a BC of 0.475. This means the .30-06 can deliver more energy and accuracy at longer ranges.
Effective Hunting Range
The effective hunting range for Roosevelt Elk is typically considered to be 200-400 yards. Both .308 and .30-06 can deliver a clean shot within this range, but the .30-06’s longer effective range makes it a better choice for longer shots. For example, at 400 yards, a .30-06 180-grain bullet will retain 95% of its initial velocity, while a .308 165-grain bullet will retain only 85%. This makes the .30-06 a better choice for hunters who need to take longer shots.
Ballistic Tables and Charts
When choosing between a .308 and a .30-06, it’s essential to consult ballistic tables and charts to determine the best rifle and ammunition for the job. The Federal Ballistic Calculator and the Sierra Bullets ballistic tables are two reliable resources that can help hunters determine the best rifle and ammunition for their needs. By consulting these resources, hunters can make an informed decision about which rifle and ammunition to choose for their Roosevelt Elk hunt.
