Mr. Martin, the "Pet Loads" book I have weighs about 35-40 lbs. and dates from maybe the 60's to the late 90's. I know nothing about the .358 Win. but do have a 30/30, 30-06, 7-08, .243, .44 marlin, 7mmwsm, 38-.357, 9mm, 45acp plus a couple of .22's. He addresses all of these except the 7wsm and the main flaw I find in his data is that it is dated and they don't make some of his main powders anymore. I am not an expert reloader as I've been at it about 5 years so I can always learn something even though I may not be loading for that caliber or that length rifle barrel. Maybe I'm easily fooled but I'm amazed at how he overcomes some of his setbacks. I'm also surprised that there are not more type errors for a book that has thousands upon thousands of words and #'s. If you think his stuff is for beginners then maybe that's what I am because I sure enjoy it. BM
