[QUOTE="RockyRandy, post: 2896516, member: 108446"] I'm Back, I feel your pain and have been through it all. The hornady 4dof program is awesome, but remember garbage in garbage. I have bought and used them all but what Hornady has done for free is outstanding. DOPE, Distance Of Previous Engagement. You have to know exactly what your gun is doing at different distances.100yds 400yds 600yds 800yds A). The most important piece of a perfect zero. is a Kestrel 2500 or better model because the environment condition are important. The elevation from sea level will change everyday and the 2500 for $160 bucks will give you everything you need. You have to take this reading every time you shoot. B). Chronograph your rifle. This is the one bit of info that is true and you don't have to tune on it very much (contrary to what I use to think). C). Know the BC of your bullet. D). Scope height, measure and enter it. So now that you have all this info into the 4DOF you should be hitting really close and then to perfect it there are 3 thing to adjust in this order. 1- Scope height 2- BC of bullet 3- Speed By playing with these you can really get it Dailed in. Good luck [/QUOTE]
