Need some help interpreting OCW results on my new build. My analysis paralysis kicks in & I’m all over the place in terms of what load to develop further. I struggle with deciding if it’s my subpar shooting or the load. I shot 25 rnds of factory ammo for barrel break in & getting familiar with the gun.

22” 300wm with Alamo’s ELR reamer
H1000
215 Berger BTO 2.837 (-.020)
Virgin Lapua brass
CCI250

It was a warm 80F day so I was fighting barrel heat & mirage at times. Since having a kid I’m limited on my ability to get to the range so I decided to shoot in suboptimal conditions.

Circled shot is what I felt was a flyer at 76. I only shot one at 78.5. Never felt I hit pressure.

Graph of velocities below. Green = avg

Suggestions? Shoot another OCW? Take one to seating depth?

I'd load up 76.8 and test seating depth. Looks like a pretty stable powder charge between 76.5 and 77. I'd start at -.020 off and work back in 0.005 increments.
