If I were to buy a new Model 70 I don't think I would have it chambered in a short mag. I would definitely go 300 win mag, 7 win mag ,270 or something along those lines . A model 70 300 WSM was the first short mag I ever purchased and I didn't care for the way the thing fed ammo.You will not have that problem with a cartridge that has a a less abrupt shoulder. If your set on a 300 wsm then the only gun out of all that I have found(excluding Tikka,Savages) that will feed them slicker then grease is the Sako 75 SM action and I am sure the 85 will be the same.Bear in mind that prior to 2005 sako made a lot of 300 wsms on long actions. NOthing wrong with a BAR either in 300 wsm I haven't had one yet that didn't shoot extremely well. In your application I would look for a BAR lightweight stalker..leave the shorttrac and longtracs on the dealers shelves. They are an economy move by Browning nothing more or less and are not 1/2 the rifle. They are lighter then a Stell receiver BAR but that is it. Thus the reasoning behind suggesting the lightweight stalker BAR if you choose that route. I would take the Model 70 over the BAR personally .. BTW I think the Mcmillan stock is a nice stock but will weigh more then the Bell and Carlson stock which is a laid up stock as well. The Bell and Carlson also has better lines and handles better then any Mcmillan version they currently produce with the exception of the Echols custom stock which costs over 400 dollars from Echols and has to be bedded and painted for addtl expense..
