The LR duplex works. I took a cow elk at 380yds with one,it was as easy as splitting the distance between the dots.

Then I began to shoot quite a bit more, and started to go up into the hills to shoot at rocks and such.

Then I found that the dotz are a great hunting tool, for plinking it leaves a bit to be desired.
Then I had a M1 installed on a VX-ll 3-9, worked great for 4 or 5 shots, then return to zero was more of an approximation.

Switched to SS scopes with .1mrad turrets and a MilQuad reticle.
Game changer. Able now to correct misses accurately, and dial up and down all day with actual return to zero.

For a pure big game hunting rifle, dotz just plain work.
For the hunting rifle that gets shot all year at all manner and size of targets, turrets and matching reticle win.
