The Guat ammo was manufactured in '93, lot 6. It is very tarnished but has no corrosion. Packed in black battlepack.
The XM193PD came loose packed.
Temperature was ~70 degrees.
The testing weapon is a FrankenAR with a 16" barrel and a SRT Hurrincane Suppressor:
The Chronograph is a Chrony Beta. Measurements were taken about 10 feet from the chronograph witht the distance from the chronograph kept consistent.

Shots were fired at the rate of 1 shot every 10 seconds with 2 minutes in between the 2 tests.
I failed to observe the distance of ejected brass, however I did note that the spent primers on both test catagories exhibited standard (non-flattened) primers.
There was no noticeable difference in the recoil of the 2 test groups. Muzzle flash and noise was not obsereved because of the suppressor.
No malfunctions of any kind were noted.
I thought about not posting this info as I feel it demonstrates the quality of the Guat ammo, and I'd rather this ammo stay in stock for a while. But I share.
I know the pictures suck. Digital cameras don't put holes in things and they typically don't go bang, so I'm not too interested in getting a new one.

Hell, I'll reply, this is quite a bit faster then 193pd so it is pretty hot ammo. While I shot some back to back I have no chrony, at least you prove what I THOUGHT, which is that it's plenty fast. Thanks!
Great info, thanks for your time and effort.
Good post. I may have to pick some up.
Thanks for the info.
Here is my chrony data, with Guat and several other common rounds:
