I'm just beginning to get into long range shooting, and I wanted to lean on the advice of the guys who have been doing it for years. I've just put together a Tikka T3 Varmint .223 with a 6.5-20 50 MM Leupold Mark 4. This past week I shot my first long range targets - out to 500 yards, and it was a hoot. My current set-up has a MIL reticle, with 1/4 MOA Clicks. I've looked at a few threads on matching systems (MIL MIL / MOA MOA), and I don't understand the reason that's desirable. I'm going to build a drop chart out to 1000 yards (on my next rifle, not the .223), and if i have the correct drop on a chart, what's the virtue of a matched system? I've seen some guys saying the math is easier when using the reticle to gauge range, but at a rifle range, I'm dealing with known distances. In hunting applications, I'm using a rangefinder beyond 150 yards, so I'm wondering if it really matters? I think it's designed to make it easier without a rangefinder, but like I said, I'm new to this, so I wanted to lean on the forum's membership for advice. Am I missing something? Incidentally, if you were going to do a matched system, wouldn't MOA MOA be more desirable, since the incremental adjustments of 1/4 MOA are more precise than .1MRAD? Thanks in advance for you help.
