Personally I like the Browning .243 A-bolt Rifles,they shoot very accurate and have a low recoil,I use 100 grain Hornady shells,and a Leupold Rifleman 3X9X40mm scopeand have harvested several nice size Deer over the past 3 years!If your Wife is small and Petite you could probably get a gun in the Youth Model with the shorter stock.Another good Rifle would be a Savage .243 with the Accu-trigger.
