Just to put some numbers with this topic. There are some FFP reticles out there these days that are pretty thin. The technology to make FFP reticles thinner progresses every year. One of the problems is that FFP scopes almost always come with an illuminated reticle(market driven). Non illuminated FFP reticles can be made even thinner(all of our FFP offerings are illuminated).
That being said, our current Gen 2 4.5-27 reticles are 1/10th moa thick. In other words it will cover up 1.047" at 1000yds. The new Razor AMG 6-24 center cross hair (which will be available later this year) is .077 moa or will cover .8" at 1000yds.
This is not to argue for one side or the other, but rather just some info so people can decide for themselves.
Scott, your VHS-4315-LR isn't illuminated is it?
