Looks like the link to the Z5 BRH has gone, so I'm assuming it must have sold pretty quick.
I had the BRX on my 3.5-18 and sold it to a mate who also has the BRH. There's not a huge amount of difference between the two, but the BRX is very fine and may be a bit more difficult to see in low light conditions, or with a bit of scrub in the background. I know I recommended it initially, but I mainly shoot targets (I have the BRX and 4W reticles on my 5-25 Z5s).
Scopes can go through the post - they're classified as an optical device, like a camera lens or pair of binoculars.
The Z5 has two different models - one with a Ballistic Turret, the other without. The BT is fine for the range or when you have enough time to adjust your elevation, and can be quite handy at known distances. The BT comes in either Plex (simple crosshair) or 4W (windage) reticles. The 4W reticle is a bit thicker than the Plex.
At shorter ranges, as knowsnothin explained, your point of impact (POI) isn't going to change a lot - you'll learn to hold over at longer distances. The BRX reticle can be useful, once you learn it, as it has windage notches and Swarovski has a handy ballistic guide on its website that shows you where your POI will be. "Christmas tree" reticles, as they're sometimes known, are handy for quick shots at known magnifications and approximate distances.
You need to know that the hashmarks on the reticle change the POI as the magnification changes. At 18x, each hashmark might for worth, say 6 inches of elevation. But at 9x magnification, each hashmark is now worth 12 inches of elevation - double.
It sounds complicated because it can be, until you get used to your scope and rifle.
Mildots are the same principle. Unless you have a first focal plane scope which alters the reticle spacing with the magnification, each mildot represents one milliradian at maximum magnification. Halve the magnifiaction, and you double the distance between mildots on the target.
Now that I've confused you - lol! - it sounds to me like you'd probably get the most out of the BRH reticle. It certainly won't be a disadvantage, and it has a couple of advantages over a simple Plex reticle when it comes to windage and spot elevation.
Here's the Swarovski Ballistic Program:
https://ballisticprograms.swarovskiopti ... ic-ProgramOf course there are other scopes out there, and if you don't wish to spend $1800-1900 on a Z5, then some of the other suggestions might suit you. Leupold make good scopes in the $1000 or so range (VX3i 4.5-14x40 or 6.5-20 etc), and for less than $1000, my favourite scope (as mentioned earlier) is the Weaver Grand Slam 4-16x44 V-EBX (800656), but I also think the Meopta Meopro 6-18x50 is one of the biggest bargains out there, as I haven't seen better glass on scopes costing almost twice as much. I'm a big fan of the Meopta for the money, and that 50mm objective lets in a lot of light.
