I have read each reply carefully and have considered all of your input & suggestions. I guess there is no one clear cut perfect choice regardless of the situation or the shooter. All of my own rifles are bolt and personally my preference for moose is either 300 win mag or 300 wsm. (I have a m. 70 in 300 wsm and a m. 77 Express in 300 win mag and like them both). I was encouraged by the favourable comments on the BAR which was my original thought and I have now acquired a Browning BAR 11 30.06 Belgium made in gorgeous (new) condition and it breaks my heart to think the stock will have to be shortened to fit her. Oh well! such is life! She can shoot it and use it for a season or two and if at some point down the road when she is better informed and has a better understanding of "rifles" she can make her own decision and may wish to replace it with something more to her favour and keep the BAR as a back up (or sell it to a another lefty with a short length of pull.)
