I am very fond of the following 9mm recipe, iv fired off over 2,000 of these with NO problems.
4.2gr Unique powder
124gr FMJ Round nose
CCI Small pistol primers
OAL of 1.15
I shoot these out of my Gen 2 Glock 19
NOTE: DO NOT EVER USE LEAD BULLETS IN ANY GLOCK!!!!!! ONLY USE FMJ.!
These are my first test rounds with this recipe and it has been consistent.. This group was shot from 40ft.
