[QUOTE="trebark, post: 532664, member: 19172"] Generally speaking you do not want your turrets marked in yards. You want them marked in MOA or MILs. The reason for this is that if they are marked in yards, you will have to shoot the load that matches your turret exactly. While many companies say they can build a custom turret if you give them the ballistics of your load, I find this hard to believe. Is it really possible to have a turret that matches all the time? what if you shoot groundhogs in the summer and it's 90 degrees. Then you take the same load and rifle deer hunting and it's 20 degrees. How close can that turret be? This doesn't even consider changes in elevation, which can have a dramatic affect on trajectory. What you want is turrets in MOA or MILS. Then have a drop chart or electronic device that takes into consideration atmospheric conditions and can calculate a decaying BC as the distance gets long and the velocity drops off. [/QUOTE]
