bowhunter, I wouldn' t cancel the order. I like to have all the manuals of the bullets I shoot. There is good info in it. Just they seem to be concervative compared to others. I like have several reloading manuals due to you have always have thinks that make you scratch your head with all of them. Like Nosler, and 357Sig. They have faster velocities with heavier bullets. So its good to compare with several and make your own decision. And confidence is 50% of shooting in my opinion.
