Pistol bullets-Is bigger and longer better at long range

[bayjoe]

Just curious, is 9mm 147 gr hp more accurate at longer range that a 124gr hp?
Just so all things are kinda equal. Both loads would be middle of the road speed per reloading manuals

Define "longer range"

Generally I don't think of 9mm or any pistol bullet as a long range projectile.

Generally, the lighter bullet will fly faster and is less susceptible to gravity but more susceptible to wind. The heavier bullet is less susceptible to wind but more susceptible to gravity.

Both are Just above supersonic speed and when they go transsonic all bets are off as far as accuracy.

I've played around with Hornady XTPs and the like in 9mm and 357 out of rifles, trying to make them "accurate" beyond 100 yards. It's a pipe dream for the most part.

 

[Bojo]

Pistol bullets behave just like rifle bullets not all twists ,barrel designs , or lengths work out the same.
add in the fact that you are pushing a marshmallow instead of a leer jet , plus a super short sight radius , things get real real fast.
Most 9mm handguns shoot 115 and lower well. Few shoot 147 grain with great accuracy in my experience anyway.

I don't know but this guys seems to do ok with one at a grand..

I have had no issues hitting steel plates at 400 yds with 147 in my 9mm ar 15. I did step on them a bit,

My Sig 226 loves the 147 gr lead trunicated flat points. Shoot them in modified bulls eye matches.

 

[riflewoman]

In a GENERAL sense a longer bearing surface can be beneficial for accuracy.

HOWEVER, bullseye shooters have found that the 9mm is a fussy one. Much depends on twist rate. In general a fast twist like 1:10 or 1:12 will be needed for 147s in a nine. If you want to shoot 115s some go as slow as a 1:32…. In general though a most 9s have a lot of difficulty holding the 10 ring on the 50 yard target from an accurized pistol. They really shine at 25 yards (or can) but the recoil impulse can be described as “snappy” even at Bullseye velocities. A LOT of people get seduced, but the 9mm can be a harsh mistress.

 

[DirtySteve]

Ok, define long range. Most Bianchi cup shooters use a 9 mm but the range is a max of 50 yards. Timed but there is ample time. The X-ring is 4”..

 

[Sandstorm]

The X-ring is 4”..

And they will put them all in the 4 inch at 50 too...Further than that is a wish and a prayer.

I have an TNW Areo survival rifle in 9mm with a bushnel turkey plex 1.75/4 with 115 hap sitting on top of 5.1 gr of power pistol it is unbelievably accurate at up to 100 where I quit testing it .
10 rounds off a bag or atv seat regularly are in a 2 to 2.5 inch circle with ease.
The same load also shoots very well out of a glock 26, the magazines being the same as well.
All packed into a go bag with 500 plus rounds in it.

Very generally

have a look at this. it may answer in part some questions. using 147 xtp hornady with adi ap100.

Not sure how NZ$ converts to US$, but not appealing to me; likewise, no trigger included?

 

[MFG_BOP]

gotrdid, should have mentioned i got that cluster with hornadys xtp 147gr.

 

[garandman]

Very generally

Depending how long a range and also ones definition of "accuracy"

Snd when any bullet of any caliber of any BC goes transsonic, You are basically dealing with long Vegas odds.

Not exactly correct. The more stability the projectile is as it departs the barrel the better it transitions through the trans sonic zone. This according to Brian Litz.
You want to spin the bullet much faster than most people if you want bullets to remain stable in ELR type shooting.

SMH. Ppl love to disagree. We are saying the same thing. Vegas odds vary depending on the race / game / whatever, but they introduce randomness and chance... at varying levels. I'm not saying the bullet is gonna fly back in the shooters general direction. LOL

Egads.

 

[PhilKeil]

Take a look at the LP08 - artillery Luger. Design and calibrated to 800 meters. Might also research the orginal specs for 9mm Parabellum ammo.

Just so we’re all on the same page here-
Bullets drop at the same rate. Gravity is an equal opportunity bitch. It’s the only constant in exterior ballistics. Heavy bullets are no more (or less) susceptible to gravity. The faster a bullet leaves the muzzle and the better is retains that velocity will determine how far it flies before hitting the Earth. As for lighter bullets getting blown more by wind, that’s a topic for another day.
