The Lott isn't needed for anything except bragging rights; merely variation on a theme. A comparable rifle so chambered will cost more. The velocity isn't that much more than the WM; my Hornady manual shows +100fps at best with similar powders. If factory ammo is important, WM has a slight availability and price edge. Brass availability is terrible for both right now if you are a handloader. I would go with the WM; in fact, I began thinking of one for myself only moments before this posted... until I found out about the brass situation.
