Getting Cozy With A Crossbow
Used correctly, the crossbow is an accurate and reliable weapon.
Riding a wave of relaxed hunting regulations and good results in the field, the crossbow has become the weapon of choice for many hunters. “The crossbow market is still growing,” said Jackie Allen of Barnett Crossbows, ” and we’re happy to be part of it.”
The crossbow’s surge in popularity is good news because it enables more hunters, but crossbow hunting is not something that should be rushed into without preparation. Like all weapons, a crossbow is only as accurate as the man or woman releasing the arrow.
Hunting with a crossbow requires stalking capability, because you must get within 40 yards of the prey. But crossbow hunters have an advantage over bow hunters in that the crossbow can be pre-cocked, so when a deer is in range, the mechanics of shooting are less likely to spook it.
Two types of crossbows are in general use today: compound and recurve. Both offer advantages. A compound crossbow is capable of generating more energy, but a recurve crossbow produces less vibration and is quieter. A recurve crossbow can be serviced in the field if the string breaks, while string replacement on a compound crossbow is more complex.
Shooting either type of crossbow is a matter of drawing the string until it locks into place, loading an arrow, releasing the safety and pulling the trigger. Crossbow arrows — sometimes called bolts — are shorter and heavier than standard arrows. As with all weapons, a steady hold is essential.
A crossbow should never be fired withour an arrow loaded. Doing so can damage the bow. It’s also important to use arrows of the size and weight recommended by the crossbow manufacturer to ensure good performance.
While many crossbows make excellent hunting weapons, some are easier to use than others. The Quad 400 Xtreme is one of the most hunter-friendly compound crossbows available and is capable of delivering a 400-grain arrow at a speed of 345 feet per second. It’s available at Dunham’s in a package that includes a 4×32 multi-reticle scope, a quiver with three arrows and a crank cocking device that makes it possible for hunting.
Many factors affect accuracy, including damaged arrows, misaligned sights or scopes, hunter technique and mechanical defects. When shooting with a recurve crossbow, it’s important to achieve an even draw when cocking. In other words, if one of the crossbow’s limbs is displaced more than the other, the arrow won’t fly true. A compound crossbow will generally draw equally if it is in good mechanical condition, but care should be exercised when cocking.
Crossbow hunters should do some target shooting before going out in the field. This will not only allow time to achieve a smooth and steady release, but will also provide an opportunity to sight in your weapon and compensate for arrow drop over distance.
All crossbows have a sighting system that compensates for drop at a specific arrow speed and range, usually 20 to 50 yards. This compensation allows you to aim directly at your target. When the arrow leaves the crossbow, it drops continuously until it reaches the target. So a properly calibrated sighting device will cause the arrow to leave the weapon on an upward trajectory when you aim directly at your target. The arrow will then travel in an arc and arrive at the target.
Since arrow drop is continuous, the sighting adjustment is only correct within a specific range. But many sighting devices are gauged with multiple reference points that allow accurate aim at varying distances. Some scopes display reticles, essentially lines, while others use dots. A three-dot scope, for example, might be set up accurate targeting at distances of 20, 30 and 40 yards. Range-finding reticle scopes are equipped with a scale that allows you to measure distance from target before selecting a reference point.
Sighting-in your scope is critical and best accomplished with a stationary target and the arrow you’ll use in the field. All scopes have an adjuster for windage, which determines the targeting accuracy left and right of center, and another for elevation, which dials in targeting above and below center.
Begin by shooting from 10 yards away to make sure you’re in the ballpark. If your results are close to target center, move out to 20 yards away. IF they’re not even close, your scope might be incorrectly installed or way our of adjustment. At 20 yards, you should be able to achieve a tight grouping of three shots within a 3-inch circle.
If you can’t achieve a tight grouping, there’s no point in twisting adjustment screws. you should practice your aim and make sure you’re shooting with a smooth motion and steady grip. Once you achieve a tight circle, you can tweak the adjustments to position your grouping of arrows at the target center. If your group of three arrows is consistently to the left or right of the bulls eye, you should turn the windage adjustment to compensate. Similarly, if the group is above or below the bulls eye, you should turn the elevation adjustment to compensate. Then retest and make further adjustments if necessary.
If your scope has multiple reticles or dots, you should dial in the top line or dot for your minimum shooting distance, then the other dots or lines will serve as targeting marks for longer distances. So if the top dot of a three-dot scope is adjusted for accuracy at 20 yards, the two lower dots may will be accurate at 30 and 40 yards. Test and verify. The extra time on the range will serve you well in the field.
