I am eyeing a couple of different Ruger #1's, in .450 Nitro. They are a limited edition, with Circassian wood.
.458's and .416 Rigby #1's are fairly easy to find. And I already have a nice .45-70. The .450 Nitro #1's have "C" weight barrels. Which means they weigh only about 8 lbs, so I guess you can carry it all day, and stand to shoot it once per day
