ive never hunted hogs before, but id go with powerbelts and a max load that your gun can handle for a load, probably a load similar to what one would use for bear would be good. is the cva eclipse hunter a magnum?
being around bog hogs and the possiblility of a need for a quick reload I would defanatly select a powder that does not required cleaning the barrel after every shot.
use the load you use for deer and hit them in the right spot. we were down a couple years ago and killed 11 with everything(bow, smoke poles, rifles(.243, .270, .30-06, .300 win mag) and 2 with a pistol. they told us to shoot them in the head with everything if the shot was right and thats what most of the guys did that hunted with the rifles and inline`s and both with the pistols were in the head too. your regular deer load will work just fine for them, every pig we shot was around 125-150lbs with only 2 going over 250. they were tough to bring down but they also were not great shots. good luck would like to see some success pics
I used a 348 gr. powerbelt and 90 grains of 3f out of my flinter and the 135 pd. hog ran about 40 yards. You want to hit them just behind the shoulder. There is a dense sinew plate over the shoulder and that has been knwon to prevent arrow and even slow moving bullet penetration.
Most of my wild hogs have been killed with the Hornady 240 grain .430 XTP bullet fired from a cheap .50 cal CVA StagHorn muzzleloader. Some of those hogs weighed over 300 pounds; most bang flopped. i've also killed about 40 wild hogs using a .50 Encore and the 250 grain SST/Shockwave bullet.
A hog is not built like a deer. Many new hog hunters make gutshots. A hog standing broadside is best shot in the crook of the front leg. This is a heart shot and the hog will drop. Quartering away hogs are best shot low behind shoulder.
