[QUOTE="Alibiiv, post: 2580083, member: 69192"] When I first read the OP my first thoughts were, [I][U]"Wow a 2 grain jump in powder seems like a lot!!"[/U][/I] So that's my first take on this thread. If I'm working a ladder load I will start at 1/2 a grain below "maximum" listed load and then drop back 1/2 a grain got 3 or for different loads. I will then start at the lower end of the loads and work my way up to the load that is 1/2 a grain below maximum.
