I started to test the Prima V a couple of weeks ago, and my CZ failed during the first string. Yesterday, I finally took it apart to find out what was wrong, and while I was fiddling with the trigger with it disassembled, two spent primers fell out. I vaguely remember spilling the little spent primer bucket from my 650, but it was months ago, and I assume the 75SL was disassembled at the time. So apparently I've been carrying around two spent primers tucked away in the pistol's innards for some time, and one of them worked it's way into a problem. Pistol is fine now.
Anyway, between the very short test a couple of weeks ago and a bunch of strings I've run with my VP9, I was comfortable predicting where these loads would come in, which is why they're not full ladders. Here we go:
Pistol: CZ-75 ShadowLine
Bullet: SNS 135gr RN
Powder: Vectan Prima V
Primers: S&B
Brass: Mixed Brass
OAL: 1.115
3.1gr Avg fps - 935 fps | SD-9 | ES-21
3.2gr Avg fps - 953 fps | SD-5 | ES-18

Pistol: CZ-75 ShadowLine
Bullet: Precision Delta 124gr JHP
Powder: Vectan Prima V
Primers: S&B
Brass: Mixed Brass
OAL: 1.085
3.7gr Avg fps - 1033 fps | SD-10 | ES-29
3.8gr Avg fps - 1065 fps | SD-8 | ES-22

Pistol: CZ-75 ShadowLine
Bullet: Precision Delta .356 124gr RN .38 Super
Powder: Vectan Prima V
Primers: S&B
Brass: Mixed Brass
OAL: 1.160
4.2gr Avg fps - 1071 fps | SD-8 | ES-32
4.3gr Avg fps - 1081 fps | SD-6 | ES-20
4.4gr Avg fps - 1110 fps | SD-10| ES-37
These ended up a little faster than I expected. 4.2 gr is exactly where I want them, which is fortunate, as the 4.2gr string produced the smallest group of the day.

I actually chronoed from a bench today. Normally, I do it off hand, but I wanted to get some basic accuracy testing in, so I used a rest. I didn't swap out targets, just used pasters. The 135 SNS, the 124 ACME, and the PD .356 38 Super bullet were all exellent in terms of accuracy, with the 4.2gr string with the 38 super being a real standout. The PD 124gr JHP were good enough, but not great.
