My Brother has the lightweight BAR 30-06. It has worked without a hitch for him. For me I prefer the Remington Pump in 30-06. You should naver have a malfunction with one of those. I am a lefty also. Thus the Pump. I have used many LH Bolt guns as well. Remington makes the BDL 700 in 308 Left Hand. I would think she could handle that. My wife doesn't like recoil but the 308 from field position shooting does not bother her.
