I want to thank tnoutdoors9 for his video on Underwood Ammo's 135 grain Nosler JHP in 10mm. Five shot average of 1594 ft/s and an average of 762 ft/lbs of muzzle energy. His numbers not mine. Not yet. I plan to load my first ladder group this week when my order arrives.
I will be using Blue Dot for the powder. I will use both Fed Large Pistol primers and Federal Magnum Pistol primers. Nosler is kind enough to provide load data that they have tested. Picture at bottom.
So, there you have it. C.O.A.L of 1.260 max. 1459 ft/s from a 6" Omega barrel. As I have mentioned previously, I have two 10mm firearms. A Glock 20 Gen 4 and a Glock 40 Gen 4. The G40 has the KKM aftermarket stainless, match, 6.1" threaded barrel, Carver Custom compensator and a 24lb spring. So I might see these speeds.
I also might see some additional speeds when fired through the MechTech CCU 16" stainless barrel. Of course all of this will be chronographed against the speeds of the G20 with 4.6" factory barrel.
I also hope to do some barrier tests. The standard cast of barrier characters: 2x4, 4x4, dry wall, water jugs, etc. While those will be fun, I don't know how representative these will be of this round's self defense capabilities. Sure, it helps to know if auto glass and other barriers are genuine obstacles or not.
If only I could find a 5'10" pig (Sus scrofa) who was walking upright, wearing 4 layers of "pre-stressed" denim, Chelsea boots, a hoody, Apple watch, Airpods, holding a venti pour-over from some overpriced coffee shop nearby, and unironically robbing a 7-11. Then we could get back some 'live meat' data, a new kind of pulled pork, if you will. The questions of penetration, expansion, short ribs performance, spare ribs performance, bone-in ham performance, all the data that be wonderfully useful while not harming any customers.
