Well this is not for most,but anyone shooting multiple distances and using Strelok will follow. So with all the variables and testing how do you set up this ballistic program to line up with your particular set up? Im able to get most variables to line up but either the middle distances will be off or the middle dead on and light for the 300 plus stuff. I plugged in the velocity at different temps and played with the different BC settings and it just doesnt ever align close enough for me. So do i run two charts with one from 0 to 200 and another from 200 and beyond. Your experiences on truing will be welcome. The Russian isnt presently available!!!

I had the same issue at first, but I as able to get it pretty close when I set it to use the G7 ballistic coefficient and manually entered an appropriate value. For CCI standard or SK standard plus I use a ballistic coefficient of 0.063, and velocity around 1050 fps, depending on temperature. It seems to work ok so far out to 300+. I've shot a couple prs matches using those values and it wasn't my dope holding me back. I got a brick of SK rifle match to try next time I'm at the range, so will have to see how close my previous numbers are for it.
Just as an example, the values for CCI standard that worked for me give me 16.9 mils at 300m, and the default values for SK rifle match say I only need 15.1 mils of elevation at 300m. If I lower the default velocity for the SK to the same 1047 fps as I use for CCI standard instead of the default value of 1073 for SK rifle match, it still only wants 15.6 mils.

I generally set Strelok to match actual at 50m. Then measure MV with a labradar and a high and low ambient temperature and put those two into Strelok. Then I true G7 or RA4 BC at the farthest distance I can shoot, usually 300m or so. If the middle distances are off, the last thing you can do is tweak the height over bore setting while keeping your close (50) and long (300) values correct with actual data.
