Its one thing to develop "The Load" Thats generally not about compromise.
But if you can't get the components for that load..sometimes the goal is " With this stuff I have,can I make safe ammo that will go "Bang" and cycle the gun?"
It might not make sense to burn 100 rds of components "working up" a load if its a make-do load
I completely agree, if primers were plentiful it would be one thing, I'm not wasting my primers using up strays, when I can't easily replace them.
I have lots of primers and bullets but I'm still not wasting them on something that is unknown when I have good, accurate recipes to use.
