nd: The suggestion above for a Montana 280 AI may be the easier choice. That said it can be done with a M70 action but you have to watch what you're doing. My lightest was a bit under 7.5#s scoped on a pre 64 action wu th FW alloy bottom metal, Brown stock and #2 Krieger that Butch Searcy profiled with a "Burgess" contour. (Utah 7/08 has posted here with a clever barrel contour that is similar). I built that rifle in the 80's and hunted it all over the west and Canada.
I always use a 24" barrel.
Stocks by Brown, Bansner, or McMillan Edge should all get you there. I would use alloy bottom metal , a light scope and rings, and contour a #2 barrel as mentioned above. If you watch the details you will come in about 7.5#s. Not sure an EW will eork but never trued it.
I have the parts sitting here with a Borden Rimrock and may get another together.
