Good morning everyone,
I watch and read quite a bit of the forums on here and perhaps you all can give me an idea of what I'm looking at.
I have a Seekins Precision Havak PH1 in 300 WM that I've had trouble finding a suitable load for. Using the Berger 215 Hybrids, load length tests showed it liked .005 off the lands. Then I proceeded to try a ladder test with H1000.
These results were conducted at 380 yards at a bench with a front bipod and a sandbag rear rest.
I started at 74 gr and went up in .4 gr increments. I got sticky bolt lift at 80.2 gr and it started getting wild so I quit there. I do not have any velocity data for them; I have a Magnetospeed and it seems to affect the barrel harmonics when attached so it was not used at this point. All of these were using the same point of aim.
From what I can tell, it looks like 75.2 - 76 may be a useable node (depending on velocity) but I'm hoping 77.2 - 78.4 will also be accurate, and fast.
What I'm not sure about is why so many of these were on the same vertical plane (or nearly) despite the distance.
