I recently picked up 400 rounds of Magtech 7.62x51 M80 ball ammo from Palmetto State Armory for 50 cents a round shipped to my door.

There were some bad reviews on this ammo indicating brass sticking in the chamber. I did run into this with a build I have using an X-caliber barrel, 4 stuck out of 50 rounds.
I was very pleased to report that my P716 has eaten 100 rounds of this without issue. Sig has had this weapon back a few times and on one trip they polished the chamber, this may be why I am not seeing the problem. The ammo is giving me about 2 MOA, not bad considering it is using an Aimpoint PRO and Vortex 3x magnifier combined with fighting through my astigmatism.
It feels good to finally be able to report something positive about my 716!

Didn't try the AR-10, it is tore down waiting on parts to set up for suppressor use. Ran another 25 out of the matrix after a good scrubbing of the chamber without issue. I think it was just a combination of a dirty, tight chamber and ammo at the limit of the spec, it all checked out fine in a case gauge.
