I don’t even chrono ammo anymore. I do my load development at 500 yards, shooting a series of charges in .4gr increments. Usually I’ll get two or more consecutive charges that have same POI and small vertical grouping. I pick the middle charge weight and load development is done. Based on charge weight and published data, I make an educated guess at velocity and get a good zero at 100 yards. Then I go to 800 and use the velocity truing function in my software. I use BCs derived by Bryan Litz if I can get them and published BCs if Litz hasn’t put anything out there. I have never not had DOPE not line up using this method.

I prefer DA. Just one number to mess with instead of three. Don’t even need to use temp unless you want to know when you’re going transonic.

If my people, who are called by my name, will humble themselves and pray and seek my face and turn from their wicked ways, then I will hear from heaven, and I will forgive their sin and will heal their land. 2 Chronicles 7:14
