I have had four sets of low 1" Talley one piece on Vanguards and they all have been just fine with the Leupold's sitting in them.
Since the Z3 would not fit using Talley lows I found a VX-2 3-9x40 LR that's been in the back of the safe for a couple of years I mounted and took it to the range. My problem not getting it bore sighted at home must have been my laser bore sight, I popped the bolt out did a quick line up at 100 yards and had no problem.
My new Vanguard Wilderness 240 mag shot great!! using Weatherby 87 gr ammo I took a fouling shot at 50 yards then 2 at 100 yards that were touching each other.
Gave it a good cleaning switched to factory 100 grain partitions that grouped under a inch. Another good cleaning and 3 more than did the same I love this new Vanguard!
Looks like I will need to order medium talleys to use my Z3 3-10x42.
