I guess the expense thing is relative. This time of year I am out shooting two or three times a week, and I shoot between twenty and two hundred rounds per range session in various calibers, so $40 a box factory ammo seems pretty expensive to me. I am guessing from your posts you don't re-load, if you do, the suggestion of the .458 makes a lot of sense. Another possibility in the Ruger #1 is .458 Lott, you can still fire .458WM and load it up or down, and you have the versatility of being able to use all the versions of the .458. Ain't guns fun : )
