This week's clip features Dave answering viewer mail. The question is "what is your favorite .338 caliber?" And, once again I am amazed at the profusion of centerfire calibers, even, as in this case, when they are all the same diameter. In fact, my Blue Book Publications "Ammo Encyclopedia" lists eight different .338 calibers, ten .338 wildcats and a few proprietary .338/.340s as well. No wonder Dave's predecessor Warren Page, reflecting on the early days of his gunwriting career, said: "I damn near wore out the decimal point on my typewriter."
