Hey guys, new to the forum!  I dont have much experience scoping rifles.  I have a remington 700 bdl in 7mm rem mag.  I will be doing some target plinking and hunting some deer sized game, maybe elk someday.  Ive seen some scopes are set up differently for magnum, why is that?  For example, a nikon BDC, the top reticle is set for 200 yards for magnums.  If i get a scope with a basic reticle, how do you adjust for shots 200 yards+?  I appreciate the answers and any advice(scope brands, magnification,reticle,etc.)

Any kind of reticle that has marks for different yardage is only going to be accurate at a certain power depending on the caliber and load. This is with a second focal plane scope such as the Nikon. Take a look at reticles like the Zeiss Rapid Z and watch some vids on how they work and you will get the idea.

On first focal plane scopes, it looks to you like the reticle gets larger and thicker as you increase power but it actually stays the same so it's easier to figure your marks, especially if you have mill dots or such.

Many people prefer to just twist a target turret however many clicks they need to at any yardage as they have already shot at those yardages and know how many clicks they need to adjust both for windage and elevation.

Leupold makes a CDS turret that is calibrated to your specific load and you just dial the yardage.

There are also zero stop turrets that may have a few different stops that you can adjust to stop at how ever many clicks you have tested for at 100, 200, 300, etc.

I prefer mill dot reticles with matching turrets over BDC reticles because for long range shooting, BDC rarely matches the particular bullet/velocity you might be using. The BDC reticles usually have a series of circles or marks below the cross hairs representing holdover for different ranges (as Clark said only useable at a specific magnification on SFP scopes). Unfortunately even if the BDC happens to reasonably fit your rifle/cartridge combo the aiming points below the crosshairs are too imprecise for longer ranges i.e. they cover too much of the target.
Just my $.02
There are some very good YouTube videos on scope selection if you don't have your heart set on BDC reticles.
