I’m going to give the data dump I get when I play with the Labradar. First, I will give my general speculation regarding what the Sig 365 ammo is about.
Based on performance from my Sig 938 (barrel .1 inch shorter than 365 barrel), I am guessing that the Sig 365 JHP ammo is delivered with a projectile designed to perform best when it hits between 1000 feet per second and 1100 feet per second. Average velocity out of my 938 was 1075 at the muzzle and it tended to carry at least 1000 fps through the 50 yards I tested. Barrel length’s impact on velocity (see two 5" barrel and Sub2k barrel results linked below) suggested powder is loaded like any other defensive load so I infer that the projectile is tuned to perform at the lower velocities achieved in the shorter barrels. Note: with the fancy box, it could just be purely marketing and I’d call on Paul Harrel to show me what it does to his “Meat” targets if Sig won’t just give us their design specs.
You will see data for 115gr Blazer Brass as well as the 115gr Sig 365. I picked the Blazer Brass 'cause it was the only 115gr 9mm in my stash. It is round nose plinking ammo, but the Energy and Velocity numbers were valuable as I considered the data.
Entirely unrelated, but interesting to this 1911 fanboy … the 365 ammo hits harder when launched from my STI Spartan than it does when launched from my M&P Pistol - both have 5" barrels. If I hadn’t shot all 20 rounds (20 round boxes suck) I’d be carrying my RIA 5" 1911 out to see if it’s barrel or platform causing this difference; as it is, I will probably repeat the experiment with 147gr Gold Dots launched from the 938, M&P, STI and RIA just to satisfy this new curiosity.
Dumped Data is Here:
Sub 2000 365
Sub 2000 Blazer
With a bit of luck, I got that right the first time. I did not format the spreadsheets, but they are pretty easy to follow. Everything is as expected but the Ke values are available for Muzzle (0), 10, 20, 30, 40 and 50 yards 'cause that’s how I set up the Labradar for this test. I do have some previous defensive ammo results I tried to post months ago, but I failed miserable and never got 'round to reposting. If anyone that read this far is interested, it’s as easy as posting the links to the data stored in this format, so ask if you’re curious.
