9mm vs. .40 vs. .45 distance shooting

Of the three calibers (9mm, .40, .45), which holds the best accuracy for distance?

My initial response would be 9, since you could use a light fast bullet. However, I think that the particular ammo and gun would have a much greater effect than caliber.

What kind of distance? 50 yards, 100, 200?

You can shoot any of them at distance once you know where a particular ammo will hit with your particular setup. Might not have any power, but are we talking about targets or people?

I don't shoot my handguns any farther than 100 yards nowadays (range limitation), and most of the time I don't go out much past 50 yards when I simply want to assess skillset basics (grip, sight picture/alignment, trigger control).

All of my 9's, .40's & .45's seem capable of demonstrating similar practical accuracy at those distances, using assorted ammunition & bullet weights.

Some folks might experience a preference for the recoil characteristics & felt recoil when shooting one or another of the pistol calibers, though. Just depends.

Back when I did more distance shooting with handguns, meaning 200+ yards and further, I preferred to use .44 Magnum or .41 Magnum.

I guess which bullet would drop the least over a maximum possible range. But as I have no idea on what is a maximum effect range for pistol ammo, not sure what distance to state.

I guess more of a military situation, so people not targets. I did not say in my thread starter because talking about "shoot people from a distance" might give the wrong impression on why I'm asking in the first place.

Personally I think they're all relatively the same, accuracy wise. Of course the slower bullets will drop faster but that can be compensated for, it's just a little tougher.

Out of those, I would say 115 grain 9mm will shoot the flattest.

With a defensive handgun, and a competent shooter at the helm, the two factors that come into play at longer distances are the quality of the ammo in usage and good sights. Unfortunately, most people don't have match grade sights on a defensive handgun.

Of course, once we factor in the other guy shooting at you this all goes out the window.

I don't think accuracy is going to be the biggest issues in getting hits, drop is.

How much would moving through the transsonic range affect pistol accuracy? Seems like subsonic ammo or ammo that stays supersonic to the target might have better accuracy. I am probably overthinking the question.

I shoot all the different pistol cartridges equally poorly, so I know for me ammo moving through the transsonic range won't make a difference.

This.

Don't forget the people killed or injured by falling bullets.

"Ed McGiven's book FAST AND FACY REVOLVER SHOOTING.

There is a section where they were shooting a 357 at 600 yards on a police Sil type target. They have pictures of guys hitting 39 out of 75 rounds. We're talking iron sights."

If we were talking pistol cartridge in a precision rifle...(Tc Encore bull barrel), then maybe it would make a difference.

But the biggest accuracy issues with all my pistols is me.

A +P+ 9mm would seem the logical load to shoot flattest.

I'm no bullseye shooter but I haven't seen any practical difference in accuracy with any handgun caliber at long distances. For me, they all group with about the same shotgun pattern on the body at 200 yards!

They don't have a nice tight group but are all tactically effective hits.

The only difference is where I have to hold to hit a man size target at that distance.

Now if we were talking about putting these three calibers in a Ransom rest or in the hands of a competent match shooter at those distances, we may see a difference.

Otherwise......

If you are talking slinging lead from a service pistol, they are all pretty much the same, the gun will matter more. The 357sig runnign hard will have an edge in drop past 50yds, but they are all dropping pretty fast past 100yds. Drop can be figured, your ability to hold for shots beyond 100yds is far more important. It's not that hard to get hits on a man sized target w/ even a "slow" 45acp out to 100yds.

For head shots under 500 yards I think they are all about the same.

I concur.

Another flat shooter you didn't mention is 10MM. Even the 200 grain XTP from DoubleTap only drops 8" at 100 yards and has more power at 100 yards than the typical .45 has at the muzzle. A 165 grain hot 10MM is dropping 6".

using 12" barrel

Would using a 12" barrel make a difference (9,.40,.45) for distance?

What powder and can we push the pressure limits?

If I can push the pressure limits to the extreme...
