.308 Winny!7mm-08 has proven to be a perfect match for whitetail. Near instant kills as opposed to 7 mm rem mag which often require a short track.
.25-06 AI pushing a Berger 115 VLD at around 3,350-3,400 FPS is some bad bad medicine for whitetails inside of 600 yards. Flat-shooting, too! Also pretty nasty for coyotes and varmints.The 257 wby and Robert's seem very popular. I'm not speaking from experience just what I see online but the .257 bullet selection is slim to none that's what kinda pushes me away from the 25 calibers. Maybe you 25 shooters can cime in on that aspect as far as bullet selection goes.
.308 Win is a classic whitetail cartridge. One of my personal favorites. I honestly don't know if (here in the south) it gets anymore classic deer hunter than .243, .30-30, .308, .270, and .30-06. Any one or several (possibly multiples) of those 5 cartridges can still be found at all times in a deer camp here in Alabama..308 Winny!
