Only problem it's not flat...But it does okay to do load data. But can only shoot out to 500 yds =( No wind but on Sunday lots of mirage.
500 is enough to get some solid data at the 50's and see where it matches up with JBM and you can get a pretty decent guess as to what you will do at other distances. Crank the power of that big ole NF down and you wont see so much mirage.
