Maybe a typo?
Maybe 880 was really 980/990?

Speer 200gr +P GDHP in 3" Kimber
I stayed after work last night and chronographed a box of Speer 200gr +P Gold Dot hollow points in my 3" Kimber Ultra Carry CDP II and 5" Les Baer Premier II. The range is indoors. Temperature was right around 70 degrees. Chronograph was 12 feet from the muzzle. The lot code on the ammo is 5402-01.
Velocities from 3" Kimber in order of firing:
1. 911 FPS
2. 896 "
3. 965 "
4. 898 "
5. 927 "
6. 1189 "
7. 934 "
8. 896 "
9. 927 "
10. 1141 "
11. 947 "
Velocities from 5" Baer
1. 996 FPS
2. 1035 "
3. 1052 "
4. 1054 "
5. 1045 "
6. 970 "
7. 1032 "
8. 1010 "
9. 998 " |
Those velocities sure do jump around a lot!
What's the lot number on your ammo? The stuff I tested a while back was the same way in .45 ACP.
The 230 and 185 grain was rather consistent but the 200 +P did the same thing for me.
Coincidence? A fluke? Or is this a sign of a potential problem with this ammo?
I'm not jumping to conclusions but this isn't the first time I've seen this with this load.
Interesting.
