Ackley didn't develope many, maybe even most, of the loads shown in his books. Some of the loads are ridiculously hot in most rifles. I got a set of Ackley's books when I was fifteen years old and read them constantly. In his manual Ackley says many of the loads were "submitted". By the way, it took me about a year to decide the whole bolt thrust thing was hokum. I've seen nothing in the intervening 54 year to make me think otherwise. GD
