Procedure for working up a load
I'm going to make up some whitetail hunting loads, and I'm looking for some advice on a procedure for working up a load.
I'm loading for a .270 Win. I've picked the 140 gr Nosler Accubond for the bullet and IMR 4831 for the powder, but I'm open to suggestions if anyone else has a better starting point.
What's your procedure?
How many of each load do you make up and shoot?
How much do you vary the charge by?
Do you clean the barrel between groups?
Hw long do you wait for the barrel to cool between groups?
What kind of improvement do you expect to see between loads?
Thanks for any advice.
