Since you stated "Fairly new to hunting" - if you use a ladder stand - as I also second that move buy a good 5 point vest/safety harness and use it all times. Make it your second skin.

And pick your shots carefully - Do pass on 'iffy' shots. The last thing you want is some shot animal collapsing across property lines if the 1200 acre owner is a non hunter. Taking a good shot with either rifle suffice.
