Ill state my experience and opinions, i was a hunting guide for many years free range for hogs. ive had several successful night hunting operations and excellent client recomendations. ive killed hundreds of hogs many trophy dominate 7 year old hogs. ive been on hunting shows in magazines etc. i have more hog hunting pictures then what this forumn would probably allow me to post. i am well known in texas as a guide and hunter so please allow me to state my opinions.
hogs vitals- A hogs vitals are tucked forward of the leg the heart is right at the elbow slightly forward. You almost have to miss low to get the heart. if you go up the leg and no higher then 1/2 way up slightly forward you will be in the lungs, if you go behind the shoulder at a broadside shot you will miss the viatals. however a slightly quartering aiming for the offside leg will give you a good double lung. the key to taking hogs is getting a hole all they way through them and blood on the ground, unless you hit brain or spine and disable them in that manner. In texas its HOT!! hogs wallow in mud, the mud bakes on to there hair and becomes bricklike. so for example you have to get a bullet through the baked on mud through the hair then (shield grissle plate- its really a big callous from rubbing lice and fighting) through the fat into the vitals and hopefully out the otherside. single lunged hogs can live a long time.
Hogs senses- there noses are excellent, hearing is excellent and there eyesight is not poor they see movement very well may not distinguish human or what not but they detect movement incredibly well almost a 7th sense.
hogs are omnivourous- which means they eat plant matter eat animal mater and curioun- which is dead animals.
a 100 lb hog is a different animal then a mature 300 lb animal or bigger. the key to harvesting any hog is shot placement. there is no substitute for hitting a viatal. a .50 with 177 gr rounjdball will take a huge hog given you hit the hog right, however a .62 through the guts is gonna leave a wounded mad hog. shot placement is key. ive guided hundreds of hunters from using longbow to a 500 Ne double rifle with every caliber in between. looking at my notes ive guided 47 hunters with traditional black powder rifles with 90% shot oppurtunity and 75% recovery rate the fails were from using saboted bullets the succeses were from a patched roundball and conical. conicals provided more pass throughs more blood on the ground and higher recovery rate.
my advice would be to take whatever caliber .45 and above that you shoot the most accurate. i personally prefer big heavy conicals, however ive got some .50 cals that shoot patched roundballs excellent. i would not hesitate to shoot one in the heart with a .490 roundball
that being said ive got 2 .54 cals sighted in a white mountain carbine and a lyman deerstalker. ive got some big hogs on my places im gonna put my traditional muzzleloaders to the test as soon as this rain stops, over a month of non stop rain only 3 days break in that time. i hope this has helped ill post as many pictures as allowed to help another learn
