The best I ever did on the old qual course with the pistol was 392, with the rifle it was 243. The day I shot 243 I was stoked, until I got back to the shop and found out that two of the other guys in the shop fired 244 and 245.
This was out of a shop of 11 guys.
I retired with 13 consecutive expert awards with the rifle and 9 with the pistol. I wanted to have 20th award expert when I retired but, they stopped letting me shoot the rifle after going over 14 years as a Gunny and they stopped letting me shoot the pistol after 20 years.
What really helped me was doing the Combat Marksmanship Instructors course and the CQB course at SOTG a couple of times. I figured out that in the three years I was with the MEU(SOC) I fired around a quarter million rounds through the M9, MP-5 and various other weapons. I really miss the days of unlimited free ammo to shoot.
