My first moose, and the first for all three of my older brothers, five in total. Ruger M77 tang 243.
It sits in lockup, i have better choices. Hasnt been out in years, never to be sold. It was my oldest brothers, sold to #2. I paid a substantial price to keep it from being sold by SIL.
Almost zero recoil. Super light. Should be limited to Sub 300lbs animals, unless close range.
Personally, whatever you choose, if it was 243, you wouldn't regret it. Rest assured, many people struggle with this choice, if you come to a place of moving on. You would have no problem selling, and recovering most of your investment.
