Re: Trajectory Correction...
Either way will work for you.
I prefer to work in clicks instead of the MOA. I think it might be a bit quicker. In reality I use a combination of both at times.
If my "click" chart (taped on the side of the rifle) calls for a certain amount of clicks, you simply dial that amount.
Knowing that one complete revolution on the Leupold has 60 clicks or 15 MOA, I find that the clicks are more direct and accurate and eleminates the need to calculate one more math transfer in your head.
For instance, If your "MOA" chart calls for 20.7 MOA you must figure the .7 added to the 20MOA and you have to Multiply the .7 Times 4 to get 2.8 (round to 3) clicks added to the 20MOA or 80 Clicks. Total now is 83 clicks needed.
So you are going back to clicks even though you are starting out with MOA.
Why not just do the clicks to begin with or a combination of both?
Use the same senario as above with clicks. Your "click" chart calls for 82.8 (round off to 83 clicks) make one complete revolution plus twenty three and your there. You can also go this way, one complete rev is 15 MOA plus 5 More MOA plus 3 clicks.
Remember some scopes such as Unertls and the old B&L with Kuharsky Rear mounts are 50 clicks in one revolution instead of 60 like the Leupold has. That's 12.5 MOA per revolution now. In this instance it is MUCH easier to go with clicks for me.
When using clicks you don't count 1 click, 2 clicks, 3 clicks and so on. If you know the chart calls for 65 clicks, you spin one quick revolution plus 5 clicks rapidly. Much quicker for the user insted of dialing up 16.2 MOA.--Your back to 16 MOA plus .2 X 4 = .8 clicks or round off to 1 more click needed.
Whatever a person is more comfortable with will work for THAT individual.
Pick the way that is "best and quickest" way for "you."
That's why we are all different.
