Vulcan 3 .30 with dnt 5x20 lrf

I have exactly what you are getting but with a Riton 4-32x56. I have the Zulus you want on a .25 and the DNT TNS 226R on an EVOL 30. I can easily hit the steel targets at 235 (my range limit) consistently and not bad grouping. The gun/scope combos are way better than me so a good shooter could whittle them down.

Saying that, I use the 3-12 LRF way more for < 70 yard shots due to a wider FOV.
