I Tested this on both 17 hornet and a 204 Ruger, ranges 50- 250 (17) , 100-350 (204) on pdog targets. The toughest are pdog peeking out of mound hole with only eyes and area above showing. I adjusted for wind BUT only dialed for elevation I had outstanding results on these tough targets.
I used a silencerco Range LRF, the PH clickless zero was giving me 10 yard resolution on dial as displayed on HUB. Burris claims 1/10 MOA resolution of turret position as measured by optical encoding, and I believe that.
i am testing the PH for possible PRS use. One appealing feature is MOA mode, where the raw position of turret is displayed in HUD. ie, not an adjusted range. That’s handy where you know range, you can dial, observe the turret value in MOA on HUD, along with level indicator while viewing target.
I have run same tests with Revic PMRs, both MOA and MIL versions. i’ll compare different brands if anyone is interested
