ropsitos Posted September 6, 2016 Share Posted September 6, 2016 Is there any sort of general consensus on dot size for this application? Thinking that I would assemble an open div rifle that I would also use as a "precision rifle", so optic would be something like a 3-9 or 4-12/16 or some such. I recently picked up $300 work of Cmore gift cards from the FN 3 gun match (thanks FN and Cmore) so I'm thinking an RTS2 would be interesting. They come in 3, 6, and 8 MOA. Based on the below, and the numbers primarily at the 50yd distances, I was thinking a 6MOA dot would work out nice. thanks bob RTS2 Dot Size, in MOA 3 6 8 target distance MOA 8 100 8 8 50 16 8 25 32 6 100 6 6 50 12 6 25 24 4 100 4 4 50 8 4 25 16 Link to comment Share on other sites More sharing options...
Flatland Shooter Posted September 6, 2016 Share Posted September 6, 2016 Going with a scope that the low end is higher than 1x or 1.5x complicates things a bit. Typically I only use the offset red dot for targets within 40 yards when I need to have the scope set for a higher magnification. The red dot saves me the time needed to throw the cat tail back and forth. If all targets on a stage can be effectively shot without adjusting the scope, the red dot is not used. Since we are looking at targets within 40 yards, consider using the same dot size you have on your open pistol. In my case, I run 6 MOA dots on both.

ropsitos Posted September 7, 2016 Author Share Posted September 7, 2016 For a given target size (using inches in my table for target diameter), bringing the target closer to the shooter increases the MOA, and I am comparing that apparent target size, at that distance, to the size of the dot. for instance: @25yds a 1" group is 4MOA @50yds a 1" group is 2MOA @100yds a 1" group is 1 MOA @200yds a 1" group is 0.5MOA. http://www.indecorous.com/bullseye/moacalc.html Link to comment Share on other sites More sharing options...

At 200 yards? Link to comment Share on other sites More sharing options...

When I read it the first time, I thought you were saying that a fixed dot size covered a larger area (higher MOA) on closer targets. Link to comment Share on other sites More sharing options...
ziebart Posted November 1, 2016 Share Posted November 1, 2016 For me it is the brightness of the dot. I have a 3 MOA dot and it is bright enough most of of the time. Sometimes I wish it had a little more pop to find it quickly. I have been using a 1-6 as primary optic, but am thinking about switching to a 2-10. This means using the side dot more.

iamspartacus Posted November 1, 2016 Share Posted November 1, 2016 I run a 3 moa dot. I use the side dot on everything closer than 50 yards, after that I start using my scope. Link to comment Share on other sites More sharing options...
