I read Petzal's article in the July issue about the "best" or "favorite" cartridges. I think somewhere at the beginning of it, he stated he wanted to "clear up any further confusion" on which cartridge was the "right" one for hunting whatever it was one was going to hunt.
Actually, I sent an email to Mr. Petzal and commented to him that I thought his article did nothing more than add "fuel to the confusion" of which cartridge was "the best". Funny...he didn't answer me...imagine that!
Essentially my statements to him were it wasn't the cartridge that should be looked at first...but the bullet type. First, the hunter should know the game he is going to hunt, and what type of bullet would work "best" on that animal. Would a ballistic tip (fast expanding) work best, or a controlled expanding (ie: Nosler Partition) be the better choice. Once the bullet selection is made, then the next "step" per-se is how far is the shot expected to occur? If the shot is going to be 100 to 200 yards, then perhaps a .308 or a 30-06 will accomplish the task. If it's farther, then a magnum may be the ticket.
But to simply say "if your going to hunt caribou, then take a 22 magnum".... (yeah..silly) then that statement goes just as far as his article did in "clearing up" the confusion.
