This has been an excellent load for my M9A1: 1. Brass of your choice. I have been using Federal once fired, shown here: https://www.edsbrassandreloaders.com/di ... tegoryId=4 2. Zero 147gr. FMJ's, here: http://www.rozedist.com/ 3. Winchester sp primer. Cheap and available. I get these from OMC since they are local, for a little over $17 per 1000. 4. 3.2 grains of Titegroup * Overall length of 1.125. This is an excellent, reliable, accurate low recoil load. I hope this helps somebody.
