This is my former March scope. My understanding of the mil values is that with 1/6400 the click adjustments were smaller than the newer 1/6283. Apparently the adjustments in mine were larger than 1/6283. I didn't care about that much because it was repeatable. This was to be a hunting scope and it took extreme concentration to dial out the parallax, not something worth dealing with on a hunting scope or PRS style competition scope. The other problem was that getting parallax dialed out, a clear picture, and a clean reticle rarely happened. I did not buy from bullets.com but their response was basically "these never have problems you just don't know how to set it up". Killswitch had the same observations and he has set up a few Ffp scopes.
I'm surprised people like the T1 reticle. When in precision shooting is it beneficial to have a small opening as the POA surrounded by a thick gob of reticle obscuring the target area around the POA? I can't think of a scenario I'd want that reticle in any shooting discipline.
I love the package they come in, size, shape, weight, turrets, and glass. As a functional aiming device there are many better executed options for much less $ IMO.
Did you test this at 100 yards or meters ?
