Hunter usually makes one groaner gun mistake in every book, but I didn't find one in this one (I WAS reading it fast, though). Closest I found was he made several references to "three ounce" trigger pulls on sniper rifles. That sounds light to me. I'd think one pound might be closer.
I don't have any experience with "pro" sniper rifles, but I have a Rem 700 with about a two-pound trigger on it and it's a little scary. Maybe I'm just used to heavier.
