The PMC 240s - - -
- -- would definitely be better hawg medicine, coldshot. Besides being noticibly hotter, the full weight (at least before the advent of HEAVY factory loads) and solid bullet will penetrate into various entry points of the tough animal than the lighter weight and more lightly constructed Silvertips. The Win ST is generally thought to be good ammo for deer, but the hogs have a far thicker skin, frequently a good layer of fat, and a lot of muscle to traverse before the bullet gets to the vitals. The ST is also a superior self defense round, simply because it doesn't penetrate so far and is easier to control for follow up shots.
Agreed as to the MUCH warmer aspect of the PMC 240s, though I've never chronographed any of them. As 444 stated, the point of impact is higher due to heavier weight. In a given caliber, the lighter, usually faster, bullet, will exit the barrel before recoil brings the muzzle up as far as with a heavier bullet. This was most evident at the advent of the lightweight, jacketed HP .38 Special and .357 mag loads. Revolvers sighted in for the old 158 gr. ammo most ALWAYS hit low with the 90 to 110 gr. stuff.
Best of luck on your hog hunt.
