Well, if oy uthink about it,the geneva convention requires ammo to kill humanely. Frangable bullets will not do it as FMJ will. On the battle field,we aren't dealing with soft skinned coyotes or deer. The ammo needed to meet certain specs. The only round to do it was FMJ. A tap round is just a V-max with moly on it. No way will it penetrate a helmet(at 500). Most quick kill varmint/game bullets will blow up on a mud claud at 200. There are gelitin tests on ar15 ammo faqs.
The wound ballistics are pretty much the same.
FMJ has a different design than our varmint bullets. They are solid based and yaw upon impact or shortly thereafter.The forward momentum of the bullet,when it hits,is upset and the weight of the rear of the bullet takes over,turning the buller rear first.Usually by the time it travels sideways,the cannalure causes the bullet to fragment.As deadly as a V-max on a yote. They pretty much do the same thing on bigger targets. The reason we get blowthroughs on coyotes,(IMHO) is there isn't enough coyote to yaw the bullet well. I have had one case where the 55 fmj yawed in a coyote.He did live,but not for long. I found them with holes the size of both my fists. I don't use FMJ for game but I have done it.Some yawed after hitting bone,others passed through without hitting anything hard enough to upset the bullet enough to yaw.IE,passthroughs.
The FMJ was designed to penetrate 10 inches of tissue.This giving it the le-way to go through body armour,then yaw.They do just that. Wars nowadays are heavy metal vs heavy metal.
game bullets wont cut it. Heres a cool link.
ballistic performance
Heres the specs for the round;
Have a 20 round magazine.
Weigh less than 6 pounds loaded.
Have selective fire capability.
Fire a round able to penetrate a standard steel helmet, body armor or 3.4mm-thick steel plate out to 500 meters. ***
Neat snippit from military records;
On 16 June 1962, one platoon from the 340 Ranger Company was on an operation...and contacted three armed Viet Cong in heavily forested jungle. Two VC had carbines, grenades, mines and one had a sub-machinegun. At a distance of approximately 15 meters, one Ranger fired an AR-15 full automatic hitting one Viet Cong with three rounds in the first burst. One round in the head took it completely off. Another in the right arm, took it completely off too. One round hit him in the right side, causing a hole about five inches in diameter...it can be assumed that any one of the three wounds would have caused death.
THat was a report filed by officers in SE Asia.
I learn every day. I love this hobby.
If I think further; If I was being attacked by a gang of crazy enemy,I want as much metal in the air and as fast as I can. No time for performance bullets. I want to be able to punch vests,steele,jeeps,APCs,and enemy bodies deep enough where they will surely die. No hunting bullet I ever heard of will even come close to that. Great forum you have here. /ubbthreads/images/graemlins/laugh.gif just my 02. jerryboy
