Speaking from a hunting background.....
I used hollow points for years and years. Each deer shot would run off just a little ways and die unless neck, spine or head shot. I was use to that. The hollow points explode, they throw lead out and into a very large tissue area, I have never gotten a complete bullet back.
This past year I went to a full metal jacket nickel plated bulllet. I was worried about many of the issues discussed above. After 5 deer on the ground I came to the conclusion that I had been using the wrong bullet for many years. ALL FIVE DEER DROPPED INSTANTLY IN THEIR TRACKS with the new FMJ bullets. Not a single step was taken from any of the five. The hits were so hard and shocking they just crumbled instantly. NEVER have I seen that in 40 years.
I believe this bullet change created something I had never had: a solid hit. I always shoot for the shoulder on deer as I like the effect from a shoulder hit. Meaning, I am hitting bone now and its devastating! Before with the hollow points they were exploding and this created a lack of knockdown power. These new FMJ bullets have solid knockdown power.
I carry all FMJ, I practice with it and I carry it. A person has just as many bones as a deer, and if I hit one bone, that person is going down, I'd bet money on it. Could I get a pass through? Sure I could, thats what back up shots are for.
Knowing your backstop is just a simple hunting rule that I have followed all my life. That is just common knowledge and being responsible.
