Curious which month/year you ordered or received the ammo.

You averaged 1557fps from 3 shots in a G20.

I got a 10 shot average of only 1426fps in my G20 with ammo purchased April 2019.

And I got a 10 shot average of 1519fps in my XDM 5.25" with ammo purchased late June 2019.

So regardless us firing a different number of shots, yours ran hotter. Hence the reason I ask.

Otherwise, Awesome video!

Underwood's 135's have to be one of the funest 10mm loads I've shot, always try and keep some on hand. They guarantee a huge grin every time : )

Soooooooooooooooooo.....  If I fired them out of my 6" KKM barrel (G40) I might get close to 1,700 fps??

That is worth buying a box just to find out.

I'm about to try some in my RIA - I'm looking at it for carry in our Western Deserts here in Utah.  Purely functional intentions.  I'm not going to shoot this ammo for fun... not me... never...

Interesting and well done video. I especially liked the pork ribs followed by expansion and penetration in the Cabelas flyers.

I am wondering about the velocity differences in the G29, as well as the skivved / non-skivved bullets from Nosler, and included in the same package. Many questions to be answered!
