This is a 150 grain load:

It looks interesting.
Thank you for pointing this new product out. I cannot think of a reason why it would not work well on medium and large game. The proof is in the filling of the freezer and we will know soon enough if it is all its claimed to be.
I'd be interested in seeing some gelatin tests of this ammo.
I shoot underwood in my gen 4 glock 20. they make great ammo ive never had any problems with the rounds ive used. i cant wait to see how their new round performs in gel tests. if someone tries it let us know how it works. i wonder if 150 grains is big enough for big black bears?
Probably. It's a nasty solid vs a hollow point.
