My Z5 is the 3.5-18 and my VX6HD is 3-18.
Here is my view on the Z5:
- Pros
- Very lightweight
- Insane glass. Crystal clear.
- Edges out the VX6HD at very first and last light.
- Cons
- Limits you to 13.25 MOA of elevation.
- Pain in the butt to set the zero.
- Limited "known distance" settings. If you set your zero at 200, then you can "set" the knobs to identify 300, 400, 500 yards (if you went with 100 yard increments).
- Questionable on its toughness.
- Easy for turrets to "spin" while out and about.
Here is my view on the VX6-HD:
- Pros
- Lightweight
- Damn good glass. With the exception of very first and last light, it will go toe to toe with the Z5.
- CDS offers more precise shots than the Z5. Obviously this will require accurate info for the CDS.
- Plenty of elevation travel.
- Feels more robust.
- Lots of "add-ons" that are included. This includes aluminum flip-up covers and a magnification throw ring.
- Locking turret so you are less likely to have a turret "spin" while out and about.
- Cons
- Flip up covers tend to pop up when you don't want them to. (nitpick)
- The magnification throw ring tends to get caught up on clothing and move the magnification on you. (nitpick)
- Very expensive compared to the VX5HD; same glass in the two but about 2x the price.
Ballistic info for your load:
With a 200 yard zero, you can dial to about 690 yards before you will be maxed out with the Z5. Not sure what the minimum velocity is for reliable expansion, but your round will hit 1800 fps at about 650 yards. If you believe the 1000 ft-lbs of energy requirement for deer-sized game, your round will hit that about 570 yards. Under this scenario the Z5 will work. If in the future you change your round (ex: ELD-X), you will leave 100+ yards of effective deer killing distance on the table due to the limitation on the Z5. Your shooting and/or hunting conditions will change these values.
My Setups
Tikka T3X, 6.5 Creedmoor, Swaro Z5 (3.5-18 BT)
Tikka T3X, 300 Win Mag, Leupold VX6-HD CDS (3-18 Firedot)
The VX6-HD is easier and faster to dial than the Z5. I personally have not had any issues related to dialing with either scope.
For my needs, the VX6-HD beats the Z5. The Z5's 13.25 MOA limitation is too restrictive for most modern cartridges. The Z5 will be my first Swaro product that I will be getting rid of. I love my SLC 10s, SLC 15s, and my STX 65/95. I will be replacing my Z5 with a VX5-HD.
