the one thing i never understood about custom turrets marked with yardage is the inconsistent variables. sure the constants are easy to account for, like muzzle velocity, ballistic coefficient, bullet type, bullet weight, ect. When you live in a place where one day of hunting season can be a beautiful 50 degree day with no wind and the next day be 20 degrees and snowing like crazy with a 30 mph wind it leaves me to question this type of turret. And the unit i do most of my hunting in has elevation changes from around 1350 to 2300. This dosnt seem like a big change and its really not, but if i was to ever draw a elk tag it would take me to the opposite end of the state where the elevation would jump to 4000 to 6300 ish. With all that said, personally i am not a fan of yardage marked turrets. If i was to confirm my zero on a nice day for a elk hunt with a yardage marked turret then drive across the state and conditions change dramatically and i get in some higher elevation and see a big elk at say 650 yards and dial to 650 on my turret, would it be a hit or miss when i squeeze off a round? my money is on a big miss. i have played around with this type of scenario on a ballistic calculator and it usually was a miss. in a few not as extreme cases it was a wounded animal. After looking at these variables i went with a kestrel
4500 nv with horus ballistics and a moa turret and i couldnt be happier with the results, consistant hits in all conditions!
