Default handgun caliber 100 yards?

hi all just out of curiosity which handgun caliber shoots out the furthest in the flatest trajectory. i know 45 has more powder but the bullet is heavier so wouldnt it drop out faster than a 9mm?

i found this a chart and is the bullet path column in terms of drops in inches?

im asking because most ranges are 100yards in california where i am and im just curious about handgun ballistics. not trying to do any kind of defense shooting out to 100, just for fun. also handgun calibers that are common.

I have shot man sized steel targets out to 220 yds with a G19. My hold over was just about three serrations on my front sight above the head. So I'd say that chart you found is pretty accurate and the flattest trajectory looks to be the 95gr 9mm.

10mm and 9x25 (10mm necked to 9mm) would be your best bets in a conventional pistol format.

.357sig would come next.

Gravity determines rate of fall. Speed detemines how far it goes before hitting the ground. If your chart showed the max speed per caliber it would be more accurate. But my Lyman manual shows the 40S&W 135gr bullet loaded with Power Pistol as rated at 1225 fps at max load. Your chart shows the speed and drop of only 1160 fps.

That 1160 fps in the chart is for a 155 gr bullet, but my book shows the max load for that bullet at only 1082. So, I'm not sure how accurate it is or what use it is if you cant match the load that they used.

Any hand gun is going out to 100+ yards, it's only going to be how much hold over your going to have to use to get there. Even using your chart the only difference between the slowest bullet and the fastest one in 8 inchs of hold over.

Your biggest problem isn't going to be how flat the trajectory is, it's going to be how well you can aim with the short sight radius of a 4" hand gun.

Actually, a .22lr will be flatter than most center fire cartrages. Typically around 6" drop at 100 yards with a 50 yd zero.

.22LR. It's easier than you think to hit at 100 with even mediocre calibers out of small pistols. You'll instinctively compensate for what little drop there actually is in your first couple shots by watching for hits in the dirt, and after that, you'll be ringing steel in no time.

Last time I was at Angeles, I ran out of rifle ammo and was shooting a 3" barreled P22 at the 100 yard metal plates over on the pistol side. The guy next to me was shooting an AK, and I was trading shots back and forth, keeping up with him hit for hit. He didn't look all that happy...

In this case, bullet weight is mostly irrelevant I would assume. I'm inexperienced with long range shooting, but the bullet pass is largely related to its velocity. The bullet shape, its aerodynamic profile, dictates the drag of the bullet. So 45 can have flatter path and not drop off if you can send it fast enough, which is no likely for 45ACP.

Your best bet is find a cartridge that is high velocity and low profile.

This is correct. If you can hold steady enough, you'll quickly figure out the correct hold-over. That's the easy part. Holding it steady enough to get hits at 100 yds. is the hard part. Your time would be better spent practicing a smooth uninterrupted trigger squeeze than splitting hairs with pistol caliber ballistics.

.221 Fireball?
.10 Squirel?

The force of gravity will make a slower round drop more than a faster round. It doesn't matter which one is heavier. The slower one will have a bigger drop over an equal distance.

.357 sig or regular .357 are hard to beat in handgun calibers for 100 yards.

With a 50 yd zero you’d do pretty well at 100 yds with an FN Five-Seven.

While this is true, bullet profile and weight will dictate wind resistance and the amount of momentum the bullet has. The more aerodynamic, and the heavier the round is, the longer it'll take to slow down, and you may have better terminal ballistics.

Firearms ballistics are far more complicated than just muzzle velocity, and in pistols even at 100 yards things like sectional density start to be an issue. For practical defensive handguns, however, the difference between loads really isn't that great, and there are far more difficult issues to consider than the difference between a normal .38Spl load (13" or so of drop) and the "best available option" which I suspect would be a 95gr .380 bullet shot out of a hot load in a SIG .357 which should be somewhere under 5". Specialist and exotics like 5.7x28mm or hot 7.62x25mm are a different matter, however, and I believe both of these show less than 3" of drop at that range.

As other have said, bullet drop is far less of an issue than the raw ability to hit the target at that range with a normal size pistol.

^ this.

That said, I’ve found my ability with a Five-Seven to be very close to that of a 556 pistol in terms of placement at 100 yds. The biggest issue is that the width of the front site in both cases is larger than the black of the bull.
