View Full Version : Nikon BDC for 30-06
11-28-2007, 10:32 AM
Hi, I have a Browning A-bolt 30-06 that I am shooting Federal 180 gr. nos HE bullets out of. The ballistics of this bullet say it has a muzzle velocity of 2880. What I am wondering is would the BDC radical on a Nikon monarch 4X16 work properly. Nikon recommends sighting it in at 100 yards. when you have a muzzle velocity of 3000 or less. That means I should have a mark for 100-400 and I don't think I will be trying to shoot anything further than 400. Does anyone have any experience with this and could give me some advice. Thanks

The reticle always "works". The issue will be what yardages the aimpoints are going to be sighted for. The only way to be certain of this is to shoot at those ranges until you find where they hit dead on.
Those scopes are basically set up like a crossbow scope, and in those optics, you set the crosshairs to hit dead on at your preferred range, but then you have to know where the other aiming points are...there's no adjustment for each independently.
You are within the manufacturer's recommendations, assuming the ballistics are accurate for the load/rifle combo you have. A chronograph is the only way to be sure of that.
Be aware that if you zero for 100, most of the bullet drop data tables out there will be inaccurate for you, as they are almost universally calculated based on a 200 yard zero.

owenrd , tddeangelo has it pretty much summed up . you have to shoot it to know whats going to happen . I have no experience with the Nikon . I have shot a Leupold , I think it was called a Boone and crockett , and helped figure it out .I have a couple of Burris scopes with the bullet drop reticle . they do good .the Burris only has a small straight dash for aiming points . the most I'm off is like an inch or two at a given yardage . I reload too so I try to play with the bullets to get a better match with the scope . then when I go to the next yardage it could be right on . now the Nikon has a circle for the aiming points so that gives you four places to aim from . top outside , top inside , bottom inside , and bottom outside .you should be able to get very close by using the different aim points . BUT I would say it will get confusing by trying to keep in mind what you need to use top inner at 200 . then bottom outer at 300 etc etc .or whatever it could be . if you decide on it I would try to keep using the same aim point for every yardage , you will know that you are within a inch or two and hunting big game an inch or two is close enough . it will definitely be a big help compared to trying to guess how much to hold over . the main crosshair you can use at any power setting , but the Burris BDC is set up for use at full power magnification . so in other words if I use my 300 yard mark and don't have my scope up to 14 power chances are I'll miss . I need to shoot like this at the range just to see how much difference it makes . I understand the Burris pretty well so if you buy something and get into problems I might be able to help you out .Hornady has a bullet drop chart , online , that you plug in your information and it gives you the drops . at any zero .
