Has anyone used the new reticules out there from Nikon (BDC) , Bushnell (DOA) Burris (Ballisticplex) ???????
How do you like it / them ?
I have been researching these on the web, they seem like they should work but I am having trouble understanding the way they work. Can you use the drop compensating feature on every power or can you use it only on the power that you set it up on??
Are they as accurate as the companies claim?
I would like to get one, but I would sure like to know if they have limitations before I make a purchase.
 
I may be out to lunch here but my understanding is that you would need to buy a scope to match your caliber. Furthermore, as I understand it, each scope is then calibrated for the specific weight of bullet that you intend to shoot. I believe in most cases its as simple as changing a bushing (if that's the correct term or not, I don't know) to match you bullet weight.

I have considered a scope of this nature as well but haven't gone too far into researching them. It just sounds cool...LoL.
 
I got one from Marstar for my M4, haven't been able to test it perfectly, but it seems to be fair accurate, they are designed for 55gr 5.56
 
32-20 is both correct and out to lunch ;) Leupold and other higher end scope makers will custom build you a BP reticle for your load but most (like the ones you mentioned)of them come with preset marks. Generally used on the highest power (which makes sense, because most people aren't shooting an animal out at 350-400 yrds on 3x power) and the BP marks range usage depends on the calibre and where you zero the rifle. For instance my Vortex on my .270wsm has a 200 meter 0 (the main cross hair) and then each line below is 300, 400, 500, etc. I happened to get lucky with mine and it's very accurate out to 500 meters, so much so that I am hitting 85% at a 8" gong at that range. I find for the most part they are fairly accurate, especially with factory ammo which has a generally known velocity, however there is obviously no one size fits all. So what may be good for 200 and 300 for your round may only have 350 as the next mark, and 400 as the one below that. It just takes practise, and then you will know exactly where each mark is hitting for your specific round. And once you have that, I find them to be WAY easier to shoot long range with then a standard reticle, as the "how many inches over is that" guess work is taken away, as well as trying to figure out inches overhold at a distant target.

i have one. on the plus side it is acurate. i had ir on a 308 win.
the down side is the reticles are tight together. great for bench or tripods.
i took it of and put my mil dot back on. it's for sale.
 
i've got a couple- bushnells- both in 4x12x40 one's a scopechief, the other a banner d&d= as LONG as you use factory ammo or ammo that approx factory, you're good- and yes, they have to be "calibrated " ie you can't go changing bullet weights or velocities and expect them to b be right- you get 4 wheels , one of them is a blank to take care of your handloads- but being an old hand i just hold -over and then shoot- too much fiddling- i'd rather have a graduated reticule than have to take my eye from the scope and read the little window and then go back to the scope again
 
They work reasonably well, but you have to test your rifle at the various distances to determine how close it is. The Burris one comes with a chart for various cartridges and bullet weights, but that's only theoretical and in practice may be high or low. Do I think it is a good system? Yes. I can aim right on using the various aim points and a bullet in the kill zone. Its not exact, but it beats estimating both range and holdover.
 
I have a couple of the leupolds with the LR duplex.

What I did was place the cross hairs on bullseye at your zero range and then read the dots below and then reference them with a ballistics chart.

For example, I zero my rifle at 100 yards. I see the first dot below bulleye is 3'' down, next dot is 3'' down and then the top of the post is 4'' down.

So thats zero, 3 MOA, 6 MOA and 10 MOA.

Now I match up to a chart to determine the co-responding distances.

That being said, you need to use the correct elevation of shooting, temperature and misc inputs when trying to figure it out.

Once I get that done, I'll go out to the field, setup targets at those distances and fine tune.

There are a bunch of programs you can use but I used this one since it seemed pretty simple.
