Step 1) Measure and record temperature and relative humidity.
Step 2) Run a 5 shot velocity average over a ProChrono Digital Chronograph at a distance of 10 feet.
Step 3) Run various terminal test shots, with and without simulated clothing barriers, into a block of Clear Ballistics Gel that is calibrated to 10% Ordnance Gel density. Shot distance is 10 feet.
Step 4) Run a 600 fps calibration test bb shot into the Clear Ballistics gel block and record penetration depth.

My Thoughts on This Load:
It was great to see such good performance from this load across all three test scenarios. The PDX1 performed exactly as you would expect a premium personal defense load to perform. Expansion was full and came very close to 1.5 times initial diameter in all tests. Penetration of all test shots fell within the 12 to 18 inch preferred penetration depth. File this test away in your mind as an example of what a good test result looks like.
I will circle back on this load with a test from a shorter barrel length (Shield, PM40, or G27) at a later date. For now, it's nice to know how it performs from a 4 inch barrel and that it may be a viable candidate for a short barrel pistol.
Pick or Pan:
Are you really going to make me say it? Ok, I will. Based on this test, the 165 grain PDX1 is a personal pick when fired from a 4 inch barrel. It tested really well.
Disclaimer....This test should not be considered an endorsement or recommendation for the product(s) tested. All tests represent actual performance in ballistics testing media. Terminal performance in all other media will show different results. It is up to each individual to make their own personal decision on which specific ammunition to use for their needs. It's also critically important to test any ammo in YOUR SPECIFIC FIREARM before relying on it for any purpose.
Ammunition labeled as +P or +P+ should only be used in firearms that have been certified by the manufacturer as safe for the additional pressures generated by these ammunition types.
