you never said what you are using it for or what range you what it to be good for!! The ballistic plex can be matched to almost any caliber, any bullet out to 500 yards with a one time research. You just have to choose the bullet that suits the predetermined drop. You can get the best of both worlds with a burris mill dot ballistic plex. I suggest between a 3-12 and a 4-16 for power to fit most applications for hunting.

I've used a couple of BDC scopes. Out to 300 yards they are reasonably accurate (for the 223). Beyond 300 yards, even if the BDC is calibrated for your bullit weight, the BDC rarely matches your bullit's point of impact, due to atmospheric conditions or ballistics. Just my experience.
Life's concerns should be about the 120lb pack your trying to get to the top of the mountain, and not the rock in your boot.

That, IMO, can be just as much of an argument against using a BDC reticle. There are other criteria that can go into selecting a bullet. What if you do some hunting at long distances, e.g. for antelope and want to use a 150 gr. ballistic tip but later switch to a 180 gr. partition that expands better at 50-150 yards for hunting elk in dense timber?

To be fair, you could use any bullet with a BDC reticle, you just have to be comfortable with (and remember/record) the drops at untidy distances, like 379 yards, 458 yards, 534 yards, etc.

(And I just realized this is in the tactical forum so may not be that applicable!)

ranging with bdc reticles is more knowing the drop of the load your using between 200 and 300 yds. this drop factor is provided by companys like swaro or they can be built by the shooter. As with any ranging the target ht is a must, and if shooting in high plains areas may be difficult as there is nothing to even compare the target with locally. As an example the swaro puts the top of the recticle on the back of target and eyeball down to the bottom select the grid marker. divide the target ht, by the bullet drop then times this by which hash mark is at the bottom of the target times 100 to get distance. This also works with zeiss Rapid Z reticles which can easy be used for ranging as the upper grip markings are in 2 moa constant increments. the cone of fire for a 10 inch target antelope will allow almost 20 yds in front of the target and 20 yds behind the target so remembering odd yardages isn't really a problem. Additionally exbal and zeiss programs allow the selection of turning the scope power down to hit the "ideal" combination of having all the numbers come out. The changes in ballistic impact due to atmospheric changes, temp, humidity, elevation are the same for mildot as well as bdc and don't enter into it. The rapid z 800 is capable of any hits out to 800 if the gun is up to it. I also use a z1000 in a Diavari 6x24 on a 300 wsm that will hit to 1000 yds just as consistently as any dial in technique.

And this is with just the scope, using a rangefinder with a bdc is so fast you can't work the controls fast enough, odd distances are easily handled by hold off or down on the nearest hash mark of the reticle you are using. NF reticles are a little slower as there is no index for the eye to follow (numbers). This also applys in using mildto or tmr reticles, mp8 for hold over reticles its easier to get your count lost.
