Quick Answer
Bullet drop for a .45-70 rifle is influenced by factors such as velocity, bullet weight, and barrel length. At long distances, the relatively flat trajectory of the .45-70 makes it suitable for hunting large game like elk. However, accurate calculations are still necessary to compensate for bullet drop.
Understanding Bullet Drop Factors
When shooting a .45-70 rifle, it’s essential to consider the effects of velocity, bullet weight, and barrel length on bullet drop. The typical .45-70 rifle velocity ranges from 1,400 to 2,000 feet per second, with heavier bullets like the 300-grain Gold Dot requiring less compensation for drop than lighter bullets like the 300-grain Remington Core-Lokt. A rule of thumb is to add 4-6 inches of drop for every 100 yards at longer ranges.
Measuring and Calculating Drop
To accurately calculate bullet drop, hunters can use ballistics software or consult a ballistics table. For example, a 300-grain Gold Dot bullet fired from a 24-inch barrel at 1,900 feet per second will drop approximately 11 inches at 300 yards and 43 inches at 500 yards. Hunters can also use the “Mil-Dot” system to estimate bullet drop at longer ranges. By measuring the size of the target’s reticle and adjusting the scope, hunters can make precise adjustments to compensate for bullet drop.
Compensating for Drop in the Field
In the field, hunters can compensate for bullet drop by using a scope with a bullet drop compensator (BDC) reticle or a mil-dot reticle. By placing the reticle’s reference point at the target’s height, hunters can estimate the point of aim and make adjustments to compensate for bullet drop. Additionally, hunters can use a shooting stick or bipod to stabilize the rifle and make precision shots at longer ranges.
