Re: Turrets for nikon monarch ?
Chi, The Custom Turret usually does off greater distance then the BDC reticle. With the .300 RUM you would choose the 200 yard zero with the high turret's and it will give you 930 yards. Pretty long shot especially if there is wind.
As for atmospheric condition's affecting your shot. I would suggest going into Spot On and changing the atmospheric condition's to the extreme's you might encounter while hunting. From temp., elevation and humidity, see what change's you get in bullet drop. I hope this help's? Please drop me a note if you have other question's.
I wouldn't under estimate the accuracy of Nikon's BDC reticle. I have shot 4 inch jar's of Tannerite with stock rifles to 600 yards and harvested a KS doe this past winter at 586 yards,my longest shot while hunting. I know for some that doesn't mean a lot, but a lot of factor's to take into consideration when making a longrange shot,especially when you are planning a 1 shot stop.
