Here are some of my thoughts on bullets.
Full-metal-jacket (solid) bullets penetrate too much, zipping through with minimal tissue damage.
Frangible varmint bullets break up quickly. Sometimes this destroys heart/lungs for a quick, clean kill, but sometimes it merely ruins a bunch of meat without reaching the vitals.
Soft points (traditional cup-and-core bullets with soft lead cores in thin metal jackets) can mushroom perfectly, break into two or three pieces, or even flatten like a pancake, depending on where they land.
Bonded-core bullets usually expand less but retain more mass for deeper penetration.
Controlled-expansion bullets—either via internal walls, bonded cores, monolithic cores or combinations—expand 1.5-2X, retain 90 percent or more mass and pass through, even after striking major bones and muscle groups.
What bullets should you use? The ones you believe in. Just understand their limitations and don't expect any to drop game in its tracks every time.
Below is some examples from barnes web site. granted this is lab info but it give you an idea of some accuracy comparisons. this of course if subjective. i have held off the long range hunting for the very reason Bergers, SMKs, Swamp Works, Nosler Custom Competition......on and on...........are match bullets not hunting bullets. In my opinion they are all great for accuracy and competative shooting. However this isnt competition this is hunting. And if your hunting shouldnt you use a hunting bullet. I beleive given time the market will follow suit which they have. FYI Nosler i beleive just announced what i call a Berger Killer..... its the Accubond Long range. And barnes is following suite with the LRX high bc hunting bullets. I love two holes in my animals and in my opinion controlled expansion is best....to each there own.
