I guess my main thought process is that if tipped bullets were really the cat's meow....then why does every single military in the world refuse to use them?
Our military, and that of most other countries, follow the dictates of Declaration III of the 1899 Hague Convention that states:
"
The Contracting Parties agree to abstain from the use of bullets which expand or flatten easily in the human body, such as bullets with a hard envelope which does not entirely cover the core, or is pierced with incisions."
Signatories at the time were worried about the new smokeless powder/jacketed bullet technology and "dum-dum" expanding bullets being somehow "inhumane". Considering how the machinery of killing has increased in type and efficiency since then, it is a little bit of a Victorian oddity in today's world.
Therefore, since then, the military of the various world powers use FMJ bullets in order to comply. Interestingly, the U.S. is not a signatory to that Convention but complies anyway. Because the Sierra Matchking and other match bullets feature a tiny HP you would think that they wouldn't comply. However there was a domestic ruling stating that because that type wasn't
engineered to expand, they were allowable for sniper use by U.S. troops.
Plastic-tipped bullets that were pioneered by Nosler and made by just about everybody now are a plastic tip over a fairly large HP. The tip acts as a initiator as well as protecting and improving the streamlined characteristics of the bullet. Because the weight is usually farther back than in conventional lead-tip SP bullets, there seems to often be an accuracy gain. They also tend to often be "softer" and expand quicker - everything else being equal. Remington had an older, but similar idea in the Bronze Point, but the newer bullets work better and are more consistent.
FMJ bullets have an open base where the lead core is inserted (and close tip), while hunting bullets have a closed base (and open tip) and the lead core goes into the jacket from the front in forming. Because of this, FMJ bullets have metal to the tip. They are also a lot cheaper to make. A plastic tip would gain the military nothing in a non-expanding bullet. Some military FMJ bullets are designed to tumble when they strike flesh (not before as some people might tell you). This is a way around the Hague that makes the wound bigger. The British .303 and Soviet 5.45x39mm bullets are a couple of examples of this engineering.
Therefore, what the military does, or has to do - and what a hunter need in his bullet - are two separate things and need to be viewed in the proper perspective as apples-and-oranges.
Other than some FMJ bullets made to "save fur" in varmint calibers, the only FMJ-type bullets are in large caliber big game bullets for use on heavy, thick-skinned and boned animals like elephant where straight and ultra deep penetration is desired.
