Hornady 168 A-Max SuperMatch Ammo in 16" DPMS 308??

[YWHIC]

This is the newer Hornady 168gr A-Max Superperformance Match (80964).

its got more zing at 2840 FPS, then the regular 2700 FPS 168gr A-Max..

Anyone shooting this thru there DPMS 16" types??

I got a 16" Heavy Barrel and want GOOD ammo for out to 600 yards..

I'd prefer to stick with Hornady and after comparing notes.. the 150 SST is also on the top of my list.. though ALOT of people say the DPMS perfers 168gr + ammo.. and the SST had issues with PRIMERS falling out supposedly..    ???

Any feedback with actual users would be good.. at $30/box I want to get this RIGHT...  :o

You don't need the Superformance ammo to get to 600 with a 16" barrel. The regular 168gr Amax load will do just fine.

I've shot the 178gr Superformance load out of a number of 16" gas guns and results have ranged from just some extra recoil to smoked and popped primers. In fact, I ended up trading Hornady 400 rounds of the 178gr Superformance for the same number of 168gr Amax standard loads.

As I understand it, Superformance ammo gets its MV boost from extending the area under the pressure curve, meaning pressures stay high for a longer period of time than with normal ammo. This can have an adverse effect on some gas guns, especially ones with shorter gas systems.
