Having recently purchased a Competition Electronics ProChrono Digital Chronograph, I must say that this is one of the best investments I have made as far as my reloading tools. And it was only $95 at many online sources. So I was able to finally verify my hand loads, and am pleased with the results.
9mm Polycoated bullets from Eggleston Munitions
The following test results were using 147 Gr Round Nose (RN) Polycoated bullets (.356”) and Alliant Powder’s Power Pistol, shooting through a full size M&P 9.
- 4.3 Gr powder at OAL 1.14” – 965 fps – PF 142.00 (unsuppressed) – Note: This is too hot, especially for the sub-compact size pistols.
- 3.7 Gr powder at OAL 1.14” – 875 fps – PF 128.77 (unsuppressed)
- 3.7 Gr powder at OAL 1.14” – 910 fps – PF 133.48 (suppressed)
The lower charge is what I shoot suppressed, which works very well. The hotter load produces too much splash back suppressed, but works great in my unsuppressed M&P full size, compact and Shield.
The following test result was using 124 Gr Conical Round Nose (CRN) Polycoated bullets (.356”) and Alliant Powder’s Power Pistol, shooting through a full size M&P 9.
- 4.8 Gr powder at OAL 1.13” – 1120 fps – PF 138.88 (unsuppressed)
Note – When developing my loads above, I based my starting point from the Hornady Handbook (9th edition) load data for Power Pistol, using their FMJ-RN using their listed starting points. Polycoated bullets are faster than the FMJ of equivalent weights.
