I'd love to see Andrew run some of Underwood's lite for caliber hyper fast Xtreme Defender choices through his ballistics gel tests.
Specifically Underwood 10mm 100gr @ 1850 to 1950fps & 357 sig 65gr @ 2100fps ${$default_laugh_smiley}$

Summon him in here! (PM him) I will gladly send any of it... if he will run it ${$default_sad_smiley}$

Good idea, maybe fruitless but it's worth a try. Pretty busy fellow between his own page & the TFB stuff he does.

I would be most interested in seeing ballistics test for these rounds, and others on ballistic dummies like those use in that great tv show Forged in Fire. The have accurate organs and bones in the torso and head!

I wonder if the lighter weight of these would cause them to veer of course more than standard weights?

Yes, they would. Bullet sideways motion (up, down, left, right) would take the same amount of force as it would to push it in free space.

African game hunters figured out long ago that big heavy solids are needed to punch through a body and keep going in a straight line.
