I didn’t gather that initially. Yeah, in that case I would have considered the load proven. Scratch that one off the list.I can almost agree with you completely. I don't feel the load was entirely experimental. As I stated, I followed the powder manufacturer's instructions closely, and have fired at least 30 rounds of this load in this gun without incident. That's in addition to the rounds fired during load work up. I don't know how many rounds you think it takes to "prove" a load, but in my mind it was no longer experimental.
