The test with the VV N133 powder was done this weekend.
I loaded up exactly the same charges as with the N530.
Same brass, same primers and same BTO/COAL and jump to the lands.
Range 97meters (~106yrd)
Temperature was -7C.
Pressure 999hPa and altitude 300m above seal level.
Shooting was done prone with bipod and rear bag.
Shots fired in "Round Robin"-style after 5 fouling shots/sighters.
All shots was fired with a Magnetospeed and here is the result from the speed data:
1.
28.1gr
Avg: 860
SD: 3
ES: 9
2.
28.2gr
Avg: 864
SD: 1
ES: 3
3.
28.3gr
Avg: 866
SD: 1
ES: 4
4.
28.4gr
Avg: 866
SD: 2
ES: 5
5.
28.5gr
Avg: 870
SD: 1
ES: 2
I was VERY surprised with the speeds.
If compared with the N530, the speed was higher with the N133 :confused:. Even at lower air temperature, and more stable. No significant signs of high pressure on any of the load.
If I take the three middle loads. The average speed is 865 m/s and the SD/ES for 15 rounds is 2/7. And this with three different loads.
. I think that the 28.3gr feels like a promising load, considering the speed data.
And the result on the target:

Once again, VERY surprised! And this time positive surprised.
If compared to the target with the N530, this is a massive improvement. I think that I can take all 5 groups and put them on top of each other and still have a smaller group than the best one from the test with N530. And this is 5 groups with the same POA, 5 different loads and all landed in almost the same spot. Ok, one flyer on the target No.1 but beside that, I am really pleased. Both with the result on target, but also with me as a shooter.
The No.3 with 28.3gr will be my load to continue with. And I feel quite confident with that.
