When a woodchuck is 75 yards away, muzzleloader hunters should use discretion to sort out whether to take the shot or get closer. I like the challenge of getting closer. SHOT SELECTION What about shooting uphill or downhill? Gravity pulls a bullet downward equally whether it's ascending or descending. Compensation-for-drop is determined by knowing the distance on the level to the hog. Know the ballistics table for the gun you are using and compensate accordingly. Lyman's Black Powder Guide is an excellent source. At normal flintlock ranges - under 100 yards - compensation is not worth worrying about. Shots beyond 100 yards require a laser rangefinder. Slow-velocity muzzleloader bullets do not possess the flat trajectory of highvelocity centerfires. That's why hunters must know the distance to game, the energy of the bullet throughout its range 60 and the drop in its trajectory beyond 100 yards. There are only two ways for a muzzleloader to quickly and humanely dispatch a groundhog. Your bullet either disrupts its electrical circuitry or its plumbing. In your house, if you turn off the electricity, the lights go out instantly. A bullet striking the brain or spinal cord of a groundhog has much the same effect. But it presents a small target that's a poor choice for muzzleloader hunters if the animal is running. The only logical aim point for a running little varmint is its plumbing - the heart, lungs, liver and major blood vessels. Trying to sneak within muzzleloader range of woodchucks is sure to present all types of shooting opportunities. All make for valuable practice for the upcoming deer seasons, and present a good chance to put your equipment to work. And those landowners who are looking to limit the damage groundhogs cause to property surely will appreciate your efforts.
