Well, so far I am only 40 pages into my 9th edition hornady reloading book, and WOW, there are so many more details affecting accuracy then I ever knew... I am looking forward to trying to dial in my 7mm rem mag more now! Always felt it should be more accurate than it is! Also have a few irons in the fire for some 38 and 357 brass to load, but I have a lot more reading to do before that! Haven't even pulled my RCBS stuff out of the box yet! The one question I have come up with so far, why don't most handguns have bullet leade? I am sure there are exceptions, but revolvers don't, (I think) or my Sig 1911...
