Reloader7RM, so it is the 4-12x Z3 your have and the Z5?

To be honest, I'm really not going to know whether I prefer the BT or a ballistic reticle until I use both. I'm new to all of this so I might just have to pick one and expect to make a few choices that don't work for me along the way. Always helpful if I can find lightly used stuff so I don't lose (much) money along the way.
