I'm trying to purchase a take-down rifle that will be accurate at ranges over 1000 yards. I would like it to be able to be assembled and disassembled in under 30 seconds and fit in a backpack. I'm leaning towards a .300 win mag or possibly .338 lapua. If anyone has anything for sale or any ideas please let me know. Thanks.
