Scope problem??

[Hudsflywater]

This pic is a pressure test for 182 HHT’s in a 300WSM custom rifle I put together. At 68gn the POI shifted almost 2 MOA?? Surly this phase to be a scope issue, or possible a receiver / chassis issue, and not a load issue? Has anyone ever seen something like this were is was a load thing???

Lone Peak Fuzion Ti Med action
Bartlein 22” cf barrel
MDT Hnt26 chassis
Lapua brass
N555 powder
Fed 215m primer
Hammer Hunter Tipped 182gn bullets

shoot the lower powder charges and see if POI does the same thing again

That’s what I was thinking, thank you!

Nothing looks out of the ordinary to me, looks like the POI is trending right as you increase powder charge. Add in the variability of 1 shot per charge and nothing looks funky.

Looks normal to me but with one shot you're not getting anything even remotely useful when it comes to comparing loads. Only thing this test should be used for is pressure.

Who cares where the POI is if they all stack next to each other? Don't try to interpolate any "accuracy" info out of this test or you'll be chasing your tail. That 66.5 to 67 would be where I started.
