I killed a piebald doe at 270 yards last season. It was the longest shot I've taken at a deer in over 20 years. I sat down and rested my rifle along side a small tree. It was also the the first time I'd used a rest to kill a deer in over 20 years. The other five deer I killed last season were all inside 65 yards and all taken off hand as is usual for me. I practice my off hand shooting regularly all year because that's the way I kill most of my deer and I'm usually close enough that I have no need to use a rest.
