I have always hunted with a 300 win mag or a 30.06 however due to financial problems(being self employeed and having no work for a year)i have had to sell almost all my guns.All i have left for deer hunting is a 270 savage accutrigger that i bought my wife two years ago and has never even been in the woods once and shot maybe 10 times.My question is does a 270 have the power needed to kill whitetail out to 400 yds?Is it sufficient to hunt the huge bodied whitetails in canada?Is it sufficient to hunt elk?
