Hornady 124 grain at 1250 fps

Hornady 124 grain at 1250 fps and speer gold dot 124 @1220

This velocity is with a 4" test barrel.

Does anyone know what the velocity of these two rounds are in a glock 17?
 
reality check

Line up ten each of any specific handgun; test same-lot ammo under similar environmental conditions.
Velocity will vary over 100fps.

So the proper question might be: "How fast is XXX ammo through MY gun?"

Ay?
 
Dave,
You're gonna run yourself nuts if you keep micro-analyzing & trying to determine minute & irrelevant differences between different bullets, calibers, velocities & sound levels.

Neither load you mention would give you any detectable difference in terminal performance based on velocity differences.
You'll find + or - variations of up to 50 FPS in either round between a Glock 17and 4-inch published test barrel figures, and can easily run into 25 or more FPS differences with either round between two different Glock 17s, and even at different times of the day.

The Gold Dot may expand fractionally better, the Hornady may penetrate fractionally deeper.

Either one would be adequate if you can shoot the gun well.
Pick something & settle down with it. :)

Very well said sir.

this is a handy chart

In order to use the chart, use the table that corresponds to the caliber in question. Locate the column that corresponds to the barrel length which the muzzle velocity was measured at. Then multiply by the factor provided in any given row to get the expected muzzle velocity out of a different length barrel. This gives you the expected muzzle velocity of THE EXACT SAME AMMUNITION fired out of a shorter barrel.
