My beef with Leopold's (sub $1300) is they mix and match turrets & reticle, AND have shyte for adjustment range. I am shooting the snot out of the FFP mil/mil Primary Arms scope and loving it! The glass really is better than the SS 3-15. And it has a butt-load of adjustment.

OP. Anyone who tells you "A" cartridge groups better than another, needs a Chuck Norris round-house to the face. This is a hobby, build something that interests you.
