For a dual purpose hunting, bench scope there are some pretty good options. It sounds like it's going to be more if a hunting scope in which case both the vortex razor lht 4.5x22 and the nightforce nx8 4-32 are great options with both weighing in under 30 Oz. If not one of them and the scope is going to be primarily hunting with occasional long range use I would be looking at something more in the 3x15 mag range
