I have been using Strelok for about the past 4 years, The layout is perfect for making fast shots, Once you have the front page loaded all you have to do is type in the distance and hit CALC and you get the Solution straight away, And the Drop down chart is the right way up Starting from Zero at the top and the MAX range at the bottom of the page, and it is perfect for confirming what the LRF is saying,
Using my LRF's factory presets it says the following,
My LRF says 495 yds 3* degrees @ 48" Low and / Or 2.7 Mils,
and Strelok says @ 495yards @ 48.1" Low and / Or 2.7 Mils.
That is accurate to within 0.0002" per yard over that distance or 2/10,000th of an inch per yard.
I Think that is pretty close @ a 1/10th of an inch at 500 yds +/-
I have tried all the others and I don't think that there is a faster or Clearer App out there, And as pointed out the retical /scope feature is brilliant and all the important features are on the first page as well as the solution and I can get the solution in under 3 seconds in MOA MRAD Inches and Clicks all at once.
Hope this helps,
John.
