RE: Duplex verses Multi Range Recticles
I like em ALOT. Several years ago I thought they were to gimicky or more for military/tactical use. But after playing with them and then using them in actual hunting situations over the last few years I have come to really recommend them and am in the process of actually having several reticles changed out in a few of my scopes.
For someone that is not shooting over 300yds (or 200 with slower calibers and muzzleloaders) they aren't needed. But IMHO if you are going to be shooting at ranges where you will be incurring more than 6" of drop, I say GO FOR IT! I haven't had any of my Leupolds changed over too the B&C but I did spend 2 days shooting at ranges up too 1k yds with several guns that had the B&C reticles. They made 500yd shots childsplay! I didn't have to work with the "windage bars" on the reticles but I am sure after a few rounds on the range and a trip or two in the field they would prove just as useful as the others.
I still like a good ol plain mil-dot as well, they are simple and work just as effectively. The main point of them is to assure a consistent aim point at XYZ yardage. I wouldn't recommend them for a beginner shooter as they would probably be more than they can manage or they might falsely instill a notion of being able to shoot farther than a newbie should. I also personally think a scope should be at a minimum of 10x and preferably 12x or greater to get the most from a multi point reticle. A 9x scope isn't much when you are talking about shooting 4,5 or 600 yds.
Good luck,
