GECO 9mm Luger 124 Grain Hexagon






GECO’s most recent addition to their line-up of 9mm Luger ammunition is their 124 grain “Hexagon” load.  This ammunition is advertised as a “match grade” load.  

The most noticeable feature of this ammunition is the “Hexagon” projectile that GECO states was created for “optimal accuracy.”   The bullet has six unique folds in the copper jacket at the meplat that create “stabilization grooves” running down the sides of the copper jacket.  CECO claims this produces a “golf ball effect.”








I chronographed the load from a Glock 19 with a factory original 4" barrel over an Oehler 35P chronograph. The muzzle velocity was 1116 FPS with a standard deviation of 10 PFS.






I evaluated the accuracy of the GECO 124 grain Hexagon load from a distance of 25 yards using a Colt 6450 with a free-floated Noveske barrel.  








When using hand-loads topped with the Hornady 125 grain HAP bullet, my Noveske barreled Colt 6450 has turned in 10-shot groups at 25 yards that have extreme spreads of less than a half-inch.









A 10-shot group of the GECO 124 grain Hexagon ammunition fired from the Noveske barreled 6450 at 25 yards had an extreme spread of 1.15”.

Huh... I was hoping this ammo would be a "inexpensive" over the counter match round....

Thank you for sharing.

They almost remind me of homemade bullets, sort of like 5.56 bullets made from .22LR cases swaged with lead.

Thanks for another interesting thread.

I have some of these from a different manufacturer, that I'm going to test against gel. Pretty sure it's the exact same bullet. The person who requested the test thought they may need a 16" barrel to expand. I was getting 1,23x out of a 16" barrel.

 

You might want to try Federal's 9MS 147 grain JHP ammunition . . .

Very Nice, Thank You.

De rien.  


...

It's most likely the same manufacturer with just a different company's name on the box.


...

I was wondering the same thing, it looks like the walls are weakened but after a second look, maybe not.

Yeah. has the same little nub on the base of the bullet. Just different box and headstamp.

 

Here was the Prime Ammunition 124gr Hexagon. Definitely not going to expand anytime soon in any 9x19mm loading..

this ammo isn't supposed to expand

I didn't think it would, but it seemed a few users (and the person who donated the box) were curious if it would.
