I agree, boot blankets, arctic shieids work well , you can go with 400-600 gram boots. Have used childs sleeping bag to put boots and legs in if you can get wide one. Good luck
Most of mine are6-6.5lbs not scoped, always puts me in under 8lbs all up which is my target wt. Most built off 700 actions or mod 70s,. Edge stock, #2 or #1 barrels. Works for me.
