RE: best deer hunting tip
The best advice I've ever recieved is this:
Never NEVER rush a shot. Always take your time when shooting. If the animal doesn't present a good shot then pass and wait for a better opportunity, even if that means not killing a deer that season.
Because I always try to adhere to this advice, fortunately I've only lost 1 deer in 18 years of hunting, and this was when I was young. The reason I lost this deer? I rushed the shot. We tracked this deer for 5 hours that night and then again for another 3 hours the next morning but never found it. It was gut shot and the blood trail ran out. It made me sick when we couldn't find this animal.
I'll never forget that, and hopefully that will never happen again. As a result, I always take my time when shooting a deer and I haven't lost a deer since.
