Hello, folks. I had a question I was hoping you all might be able to help out with. I've been playing around with a Vortex Impact 4000 weapon-mounted LRF and one thing has me a little stumped. All of the videos and instructions I can find on the LRF say that it should be 'parallel-zeroed' at 100 yards, meaning the LRF should be aligned / zeroed to paint a spot about 2.5" above the scope centerline at 100 yards. So, scope crosshairs on a target at 100 with the LRF painting a spot 2.5" above the spot on the target where the scope is pointing. I may be WAY overthinking this, but it seems that this could cause issues as you get out at significant distances. If I had just shot a target at say 800 yards, and I had dialed for it (instead of held), the crosshairs of my scope are no longer anywhere near where the LRF is pointing. If I swing to the next target, find it in the scope, hold on the target with the crosshairs (without dialing back to zero), and hit the LRF, would I run the risk of missing the target with the LRF (because the reticle moved a bunch--because I dialed--and is no longer parallel-zeroed to the LRF)? Out at 900 yards there would be potentially a 20' or more difference between where the crosshairs of the scope is pointed (if I dialed) vs. where the LRF is pointing, as the LRF is aligned with the 100 yard zero. Am I overthinking this? Does the LRF paint a big enough area to account for this? Am I just dumb and don't understand what's going on (most probable)? Thanks |
| You have to be at your zero dope (ie 100) for it to work correctly. There will obviously be a window where you’ll still lase within an acceptable margin, as I’m sure you could do the math to find out, but yeah if you’re dialed for a 1000yd shot your laser won’t be anywhere close. So either return to zero to lase, or shoot from your reticle. |
