The hotter load is way more accurate. It appears you found the sweet spot. Now you need a chrono to fine tune it.  |

You will get the same kind of results by changing the length of the bullet. No other changed where made. Same amount of powder, same primers, and same cases. It went from 3 inch or 1 MOA group, to 1 inch and .33 moa group. This is a 300 yard group. Overall length was 3.270  And then I changed the length by 0.01. Changed it to 3.280  |

I had my hands on a chrony a few months ago and almost bought it. I will probably get one at some point in time.
