Handgun hunting is the most fun you can have with your clothes on, every year I have allot of fun crawling around with a pistol or revolver. Sometimes it irritates the wife when I'm sliding to a halt, jumping out putting a group on stalk. She'll get pouty, huff and sit back in the seat and whine she has things to do at the house
Key things I have found is breaking up your outline and keeping the wind in your face. The wind is the biggest thing, if you have it in your favor, even if they see you and you don't act in a "threatning" they won't bolt on ya. Many times I've had them see me and they will move in closer trying to figure out what I am.
Something else that works good is doe/fawn "bleater" mouth call, if they see you and get uneasy, gently fawn bleat a couple times and then stop. Deer are curious and does will move in a bit to see whats up. You need one that doesn't require your hands so you can have your handgun ready, when they get close you have to be in a shooting position or they are going to bolt when you start moving around.
During the late season bucks will come in to a doe "snort" or "bleat" when the rut is getting underway. I used a call to hold the whitetail buck I shot this year, he had seen me and moved into cover I moved to get the wind right and "snorted" him up closer for a shot. The "snorting/barking" doe thing is funny, does use it when they are nervous, like when they aren't ready to be bred yet, bucks don't understand that no,means no and come in anyway. "Hey baby, you know you want some of this"
They fucking get some all right.

Close in deer and antelope hunting are a hoot.
