Just trying to find the correction or reasoning behind a few issues.
Also note that in order to try to correct the existing problem all files were deleted for a second go around - and nothing has corrected itself other then I lost a years worth of GPS recorded target positions.
The GPS system works perfect but when trying to use the local weather feature- with or without the WiFI on the weather feature does not pull anything in. Not a big deal because I can enter in the info needed - DA from another source. But still the weather program is part of the system and I'm wondering why it doesn't function.
My main concern is the Spin Drift function.
As seen in the pictures my bullets will hit 29.5" high at a 100 yard target when using the center crosshair. So I enter in the parameters zero range = 100 yards Zero Height = 29.5 which would give me a 8.1 mil hold under to hit a 1" dot a 100 yards - simple.
But when I engage the Spin Drift function the ColdBore wants the impact corrected at a 100 yards with a 4.6 mil hold to the right? We have ran this same scenario in AB, Trasol, FFS and they all start the spin drift beginning point at 100 yards with a slow correction as needed once you get out a ways using the same 29.5" vertical offset in the sight system. Versus the questionable aggressive negative 4.6 mils right out of the gate with ColdBore - from what I see it runs a strong negative Right Hold or Dial then slowly hits a zero correction at where the center of the crosshair would be at a given distance - for example when doing a hold under at a 100 yard target ( 8.1 Mils) down, the center of the crosshairs would be in the area of a 1725 yard impact. At that point the ColdBore has walked its Spin Drift correct from a strong right back to nothing at 1725 yards and then starts it's corrections for holding left as the targets go beyond the 1725 yard point. In reality this should all start from 100 yards and slowly correct the shooter as he stretches out as done in the other programs listed, not a hard right and then to point zero at 1725 and then slowly left after. I ran a Track on the same rifle, bullet profile with a zero offset correction for a 100 yards as most folks have and the difference in the left - right hold is enough to be a concern when under a time restraint and limited rounds allowed.
At the KO2M last year I had a hard copy of the spin drift corrections using a true 100 zero - no offsets and then ran the other track with the 29.5" inch offset and the spin drift function shut off in order to give me spot on vertical corrections past 3000 I just had to remember to add the spin drift required on my hard copy with the wind corrections posted in the ColdBore. At the end we parked the ColdBore and used my partners Field Firing Solutions - the least amount of thinking and re-corrections the better when under pressure.
So here are a few pictures of the screens - as stated I dumped everything and started with clean files hoping the glitches would go away but they didn't. For the folks who are running the same system enter this info in and run a test run and see what changes when you turn the spin drift function on and off as far as the corrections ColdBore wants at a 100 yards for example with the windage holdoff.
