300 Rum N570 Ladder

[DoubleGobble00]

Below are the results from my 260 yard ladder test. I really need more yardage but that's all I got. I really liked the n570. The velocities were definitely higher than h1000 and less pressure. I'd post my velocities but my chronograph was too close plus lighting conditions were not good. It didn't read them accurately.

i think your steps are too small for this big case.
at least .5 maybe bigger
86-87 is good

Assuming no pressure i like 89.5g

I didn't see pressure till the last shot of 91.3 then my bolt was sticky and ejector mark. The rest didn't show any pressure sign. It looks good low at 86-87 but I really like the velocity gain around 89.5-89.8. I'm hoping I can find a good load there.
