Short of having someone pull one, you won't find the info anywhere online. Can someone sacrifice a round for science?
This would make sense. Velocity is par with what I'd expect from 41.2gr.
It would be very interesting to measure the consistency of the load. Let's see what the differences are between the loads
Same ammunition from Norma, Tikka TAC A1 (24" factory barrel) rifle, I fired 40 shots and measured 2611.5 fps average velocity and 15.41 fps SD.
5 shots still seem too few to have a conclusion as close as possible to the truth, and always with a small number of shots I had a lower SD than the real one. That's why when I want to have a real conclusion I use somewhere around 20 sample size shots

I'll pull a few apart and see what I have. Shoots really well in one of my barrels but the ES and SD over 20-30shots gets too high. I will say if you cull 3-4 shots it's respectable for factory ammo. Problem is you don't know which rounds it will be.
