5.56mm 55gr GMX

[Rich]

I see that the 5.56mm GMX 55gr made the Doc`s list

Am I to understand that the 5.56 Superformance line was made for use in 20inch DI only
And that there was a timing issue?

So this load wont work in DI Carbines

the whole SF line is confusing so waht about superformance in 223rem loading and DI carbines?

Hornady has a 55 gr. GMX .223 in their TAP lineup.
I'm betting that it is this and not the Superformance loading.

Were did you get the data from that the SF is only to be used in 20'' guns?

Greg, spoke well of it in some testing he was in.

reading from there own website

Also I happen to buy 10 boxes of the 5.56mm SF 75gr . Hornady offer me a trade in for 75gr TAP 5.56mm
Of coarse thats been a long time ago.

I think there was a few topics on the SF 5.56mm ammo here.

yeah that's where I read it too. The stuff grouped horrendously from my N4 Recce 16". Worst I'd ever seen in that rifle.

I noticed that when I went to the website, which is why I linked to that page instead of the specific .223 GMX page.
Probably should've altered my text to reflect that, but the point was that the GMX is not limited to the Superformance line.

Hornady has produced at least three different loadings using their 55 grain GMX projectile.

Was the GMX 5.56 shot using carbine?

I know you shoot both rifle & car
