Changing lot numbers on powder

[FowlMouthA400]

Fixing to work up a load for 7 prc and I had just enough leftover powder (H4831SC) to get some test loads made. Will have to go to a fresh LB after the initial load test. Will it be a big enough change that the test will be a waste. I’m fairly new to loading. And never encountered this before.

I would say no, a bench rest shooter would probably say yes.

I would not worry unless you are very close to max, but I would also listen to Hornady podcast linked below before you spend any more time testing loads.

The truth is that stuff like OCW, Ladder, Satterlee etc. are generally a complete waste of time.

More powder=more velocity. If you load consistent ammo and shoot it through a quality firearm then it should shoot well.

I mix lots and don't worry about it.
