Jill is 5' 10" 120lbs and shoots everything we own from pistols, shotgun, and rifles. Her main rifles for Deer or larger .243 Remington Mountain DM with a Bell & Carlson stock. Nice Light weight. The a .260 Cooper, (little heavier) then a 270 WSM Kimber Montana Kevlar -super light. Get you wife a 260 in a mountain rifle. She can hunt just about anything in NA except Griz or Polar and reloading 6.5 you have so many choices in bullets depending on the twist rate.
