Help with OCW

[Macmathews]

normally these are really easy for me to read.
target was levelled with a total of 33 + 1 shots.
i noticed a little swipe on the second round at 45.4 grains. Temps are right at freezing here so I thought I'd shoot this faster.
Anyhow , please advise how you would proceed.

Did you chrono the speeds? I find that often helps in making decisions. I usually pick the fastest and most consistent speed with the tightest group.

I have not tried..
All I have is a chrony F1, would you trust that ?

POI is pretty consistent from 44.8 to 45.4.

+1 I would test around 44.8 up and down and do another OCW test

My wife thinks I only have 3 guns

I was thinking of trying 44.2 and and 45.1 maybe I'll try using my cheap chrony.
Thoughts ?

44.2 and playing with seating depth...45.1 looks good also as long as its not too close to pressure to run

I would run 44.8 to 45.4 in .1 increments 5 of each and shoot them over the chronograph.

Better than nothing but maybe not too religiously.

Thanks guys,

Your target shows that 43.0, 44.2, and 45.5 are your scatter nodes, which would make 43.6, 44.8, and 46.2 your accuracy nodes according to your verified results and theoretical results based on calculation. Since your seeing ejector swipe at 45.4, I'd verify a high node at 44.8 and roll.
