Choosing an average elevation for my Leupold CDS
Ok guys, I have a new Leupold CDS scope on my Remington Model 700 LSS 300RUM and now must choose an average elevation for the ballistic input to customize the dial for my load.
Like most of us, I hunt whereever for whatever, putting in lots of apps for multiple species all over the west. Most of my hunting will be done at anywhere from 5000' to 10,000'. Sometimes a bit higher or lower, but not much outside of that range.
My Leupold Rep tells me that the chosen elevation will pretty much hold true to +or- 2000 feet. In other words, if I go with 7500', I'll be good from 5500' to 9500', more or less. Of course, the difference will show up mostly at longer ranges, with lower elevation shots falling low and higher elevation shots being a bit high. I haven't done my homework yet to see just how much of a difference it will make, but I intend to. I am thinking that the effect will be minimal until the range becomes extended, but good ballistics charts should get me on track. I'm betting some of you guys have that info down pat.
I'm going to shoot a 180 grain Swift Scirocco with a BC of .500 at 3250 fps with a 300 yd zero.
