[QUOTE="crusier_32, post: 197378, member: 11086"] Hello, this is my first post here. Though I have been reading old threads here for awhile, and have learned allot in the process. Anyway I am getting into this long range shooting a bit, mostly with varmints. For the time being I am only shooting a .223, mostly I am just trying to learn the ropes with something affordable to shoot. Anyway the scope I am using is a Burris variable 14x with the ballisticplex reticle. For most of what I use it for (inside of 300 yds) I just use the different dots for my hold over, which works fine for the most part. I would like to be able to practice out to 500 hundred though with this rifle. At that range the dots are aways apart and estimating a smidgen high or low gets hard to do. But what my theory is though is that I can still use the dots at any range, but then to also turn the knobs so I can place the cross hair right on without any guessing. Let me run an example, and if someone could double check me I would appreciate it. Lets say I am shooting at 450 yards. The drop for the fourth dot on this scope is 29" @ 400yds. My drop chart tells me I need to have 8.85 moa of elevation. Converting 29" to moa gives me 29/(400/100) = 7.25 moa So then I would need to dial my scope up 8.85-7.25 = 1.6 moa. Burris uses 1/4" clicks @100 yds so to get clicks 1.6/(1.047/4) = 6.111 clicks. Or 6 clicks of elevation using the forth dot on the scope. Does this all sound like a sound theory or am I doing something wrong. I plan on getting out and trying this theory out this weekend. Though I have not tested this drop chart yet, and I try not to change more then one variable at a time here. This post got longer then I expected, but I appreciate any insight. Thanks, Will [/QUOTE]
