PCC loads for AR 9mm type.


Recommended Posts

My USPSA gun is a old style (short throat) PSA 16" barrel. 

 

For the 2017 shooting season I was quite happy with 147 gr Xtreme plated round nose bullets over 3.0 gr n320 (PF 132). 

 

After reading comments about lighter bullets running at higher velocities, I did a bit of experimenting.

 

For the 2018 USPSA shooting season I will run 147 gr Xtreme plated round nose bullets over 3.3 gr n320 loaded at 1.085" AOL (PF 145).  A little more recoil but less muzzle movement.  Shoots nice small groups at 25 yards.

 

I will also dabble a bit in UML (United Multi Gun League) this year using a PSA 16" new style barrel (long throat) shooting 125 gr Zero JHP over 3.8 gr  n-320 at 1.110" OAL.  I'm getting right at 2" groups at 100 yards. Velocity is 1075 fps (PF 134.8).  Gun is zero'd at 75 yards for the MTAC scope and 10 yards for the FastFire III mounted at 45 deg.

 

Last month I picked up a Taccom ULW barrel and will play with this as time and weather permit.

This load is not tuned to my PCC, I'm just shooting my Production load.

 

124gr Ibejihead, Winchester small pistol primers, 3.6gr Titegroup, 1.08" OAL, mixed brass

1204 fps (avg for 20 shots) from a Nordic 16" barrel

149PF

 

The above load gives me 134PF in my 5" X5 Allround, for comparison.
