I'm trying to figure out why it's OK to shoot a deer up to 200 pounds an not a pig up to 200 pounds with a 223.
Will a .223 go thru a ton of feathers easier than a ton of elephant? Well ok, 200 pounds of feathers or 200 pounds of elephant? How about 200 pounds of 2x4s or 200 pounds of aluminum?
I have shot a .223 in silhouette competition. Winchester 55gr soft point bullets will crater the T1 chickens at 50 meters. Nosler 55gr ballistic tips just leave a gray mark.
200 meter rams weight @ 55 pounds. The Nosler 55gr ballistic tips leave a gray mark and sometimes the ram just rings and stand there. The Winchester 55gr soft points leave a little darker gray mark but the rams almost always go down.
There is a big difference in the composition of these two same size/weight bullets.
The Noslers basically explode on steel due to it's construction. The speed/momentum cause the bullet to come apart on impact. As the bullet comes apart, the weight of the steel forces the smaller particles of bullet to bounce off. Momentum/force disipates away from the steel quickly.
The Winchester bullet does not explode. It's construction keeps the momentum centered at the impact point. This is why the chicken craters and the ram has a more sustained momentum/force that knock it over more reliably.
Footballs are made of pigskin. Buckskin (mountain man) shirts feel a whole lot softer and thinner. Deer are thin muscled and wiry, pigs are short and stout.
Imagine that Nosler coming apart at impact. How different would it be skin and bone of deer vs skin and bone of pig. Ok, go to the Winchester. Is it just going to punch thru like the cratered chicken? or come apart like on the ram?
Lots of story to sum up the .223. Most commercial bullets are made for varmint shooting. They come apart on impact. When you get to the tougher stronger military type bullets, they are made to punch holes. They are not made to mushroom like a hunting bullet and shock the animal.
Does a .223 have the capability of killing a 200lb pig? If it will knock over a 55lb steel ram at 200 meters, it will kill a 200lb pig. Will it do it every time? Or like the ringing ram, will the pig stay standing and run away? .223 won't make a very big hole if you punch hole. Small holes = small blood trail.
If I was in my truck and a pig was tearing up my property, if I only had the .223 with me, yes I would shoot it.
If I were planning on taking a trip to hunt pig to eat, and I only had a .223, I would find a friend with a .308, .30-06 or something similar to borrow for my trip.
