I was just reading up on the use of open sights and to tell the truth I find the correct use of open sights a bit confusing.
My rifle, being an old BRNO in 270win has fixed open sights that can not be adjusted (contrary to many I see on the internet that can adjust for windage), so I guess they were adjusted at the factory and fixed into place.
It has a front bead and a back square notch.
What I find confusing is the sight picture that is recommended for this type of open sight. If we look at the ZKK Owners Manual, on page 27 it shows a picture (figure 8). The image depicts the open sight picture and the top of the bead with the bulls eye of the target sitting on top of the bead. My questions being:
are all target bulls eyes the same size?
what distance would this hold true for?
on an animal at 50m or 100m where would I consider the POI to be in relation to the front bead?
I had always held the bead centred directly over what I wanted to hit (hiding the POI, like I would with a red dot). Whereas from what I have read I should be holding my POI above the bead!
I realise many will say go to the range and figure it out, but I have very rare opportunities to do so as the closest range is almost two hours away and extremely expensive. Though I will do so when I get a chance same as I did to zero my sight.
And anyway I have never been sure of what range the rifles open sights was fixed at, 50, 100, 150 or 200m? and for what projectiles?! Data on the internet is scarce for this rifle as the manufacturer is no longer the same and CZ isnt very good at answering questions about old rifles.
Does anyone shoot old BRNO's with open sights? Any data would be helpful and probably for other rifles would hold true for mine as well.
ps. (I currently have an AIMPOINT set up on my rifle and it has been zeroed accordingly for 150gr PPU's. But you never know when one needs to take off the reddot sight and rely on the open sights. Its always useful to know how things work.
