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.
Anyone shot any recent lots of this? Looking to buy some in bulk to put back. 130s or the 143 the way to go?
Shot 400rds of the 130s and so far 140 rds of the 143s. AI standard 6.5 barrel, 1:8 twist. Roughly 1 moa for both rounds and SDs in the high teens.
Not great but for a hair over a buck around which I paid and for decent brass I think it’s OK value.
That must be you or your barrel.
I am finishing up 3500 rounds of it and its held about 10-12 SD and a .5-.6 groups.
About to order another 2k for next year.

We shoot TONS of it in gasser's. The results are usually on par with ELDM, but about 30% less expensive and you don't have to deal with broken tips.
I shoot 143s but have buddies who shoot the 130s. They are the same price so I take the higher BC bullet. Its right at .304-.305 G7 trued.
