It depends on how you define power. Total energy delivered? Yes, rifle rounds, especially larger calibres, will win out, but isn't there more to it than just speed and size and the temporary wound cavity? A .22 short to the ear canal has more 'stopping power' than a rifle round to the toe.
My post was primarily referring to the properties of the ammunition. Hollow point and expanding core ammunition cut much wider wound channels than FMJ. There's a reason hunters don't often use FMJ--things like Core-Lokit are more efficient killers, meaning they're more humane and you don't have to track the target nearly as far.
Even then you may be right that the total advantage of the increased kinetic energy outweighs the benefits of hollow point and soft core ammunition, I didn't bother to check, but I still don't believe the difference is nearly as drastic as it's made out to be in most health point based damage models. I know I wouldn't want to take a Hydra-Shok to the heart any more than a 7.62.

Well that's really comparison of apples and oranges. And anti-tank gun is pretty weak... if it completely misses.
Like for like, rifle almost always wins out.
i suppose one way you could balance it for a game is with weapons "damage spread". I don't mean over range like COD, I mean each shot at a given range hitting a specific hitbox.
The AK47 round would have a damage rating of 25 to 80 for say hitting the "thigh hitbox" while the pistol does a rather consistent 25-30hp. The logic being that if it just goes through the thigh muscle and doesn't "yaw" (that is, turn sideways as the bullet is quite long an pointed and it's like trying to balance a pencil on it's tip, so it' turn broad side on doing more damage) then it'll zip through and have an effect much like a pistol, hence both rifle and pistol have the same bottom end. But there is a very good chance the rifle will hit bone or artery, where it has mass and velocity to shatter bone and sever artery (where a slower rounded bullet is more likely to literally push the artery aside unless it it's it perfectly dead on, arteries are tough).
That's how it would be from a gameplay perspective. And for things like the head which is very bony, game over man, game over.

Well, you want to look out for where hollowpoint are actually proven effective and where they are simply presumed effective.
Hollowpoints are proven effective by hunters with high power cartridges, either rifles or at the very least magnum revolvers. It's considered "trick shooting" to take down deer (similar size and build to humans in terms of cardiovascular system) with a weak weapon like a pistol or bow.
Hunters use hollowpoint there where they need and use all that power for a bullet to expand well and penetrate right through the thigh strong ribs/muscle, though heart AND lung and then out the other side, quickly draining lungs of air.
See, pistols really lack in power, kinetic energy that is. Experiences with law enforcement using hollowpoints has been less than exemplary. Take for example the 1986 FBI Miami shootout, one of the most studied shootouts. An FBI team armed mainly with 9mm pistols and .38 revolvers loaded with hollow point ammunition ambushed a pair of bank robbers, they outnumbered them 4 to one, had them cornered and surrounded. In the ensuing gunfight the FBI got several good hits with their pistol on the suspects, the hollowpoints opened up fine, but they did not penetrate deep enough. One was even shot in the face, with a bullet lodged in their fractured skull, but he was only dazed for a few minutes. The robbers almost got away in another vehicle when an agent they'd shot and thought was dead is able to sneak up on them, blast both of them in the car with a shotgun then finally stop them with practically contact shots to the forehead.
The coroner's report found the earlier shots failed to stop the killers because the expanding pistol rounds didn't penetrate deep enough. They found it was utterly trivial whether they expanded or not, and they did. But a full depth narrow wound is better than a broader shallow one. The conclusion was to go back to FMJ, or use far more powerful weapons for hollowpoints.
Really, trying to increase pistol effectiveness by making bullets only reach 2 or 3 millimetres at MOST from the radius is futile. Coronors know how people die and are debilitated by being shot, a bullet being slightly bigger (hollowpoint expansion) doesn't make it more effective, it indirectly makes the bullet less effective my more resistance, it penetrates less.
Military forces around the world haven't had particular problem using 9mm FMJ.
Hollowpoints for pistols struggle to reliably expand by 50% and then struggle to penetrate.
Rifles with hollowpoints much more reliably expand to 2x the initial diameter and still penetrate well. And standard rifle bullets, spitzer rounds yaw and fragment, which is even more destructive than hollowpoints.
So what applies for pistols in terms of hollowpoints applies double for rifles.
The difference isn't THAT dramatic... mainly because bullets are so deadly anyway, yet most people miss and don't know if they missed or the bullet simply had no effect. It does have a positive feedback, if someone is scared and causes them to miss, they panic and think they are dealing with some sort of terminator and their panic causes them to be more likely to miss the next shot.
Pistols are going to be weak in games or else they are just going to be going too far away from realism.
They can be made more powerful but when you cross that line you can do anything, it's at the cost of other weapons in the game.
I think if you want a powerful and accurate single-shot weapon in your game, that's the role for a battle rifle like M14, FN FAL or HK G3.
