Thread: Post "3 shot group" load development

So for those who have watched and understood the implications of Hornady's #50 podcast (or arrived at the same destination by another route!) what's you approach to load development when your first combinations don't work?

It's reasonably obvious that having "chosen the most suitable projectile for purpose" that changing powder would be the first stop. But I've not seen any documented experiences on how many different powders you'd try before going onto the 2nd choice projectile?

For those into this has anyone tried any combinations? Results?
