[QUOTE="Stgraves260, post: 1716109, member: 19988"] The best advice I can give is set you up a huge target like 4’ tall and 3’ wide. Just something big you know you can hit easy. One you know you can hit. You are trying to validate your range finder. The FPS that you have in your rangefinder May not match your chronograph. Face True North when doing this. I can not stress enough on how important it is to validate your rangefinder shooting true north. I used a 4’ x 4’ pieces of plywood. I put a 3 “ shoot and see sticker on the piece of wood. Use what you like. It’s just what I did. Here is some info to help you out with the math. If your adjustments in your scope are .25 MOA @ 100 yards know that at 600 yards every click will move your bullets impact 1.5”. Fire 1 round and go down to your target and see if you hit it. If you did use a ruler and measure how many inches you are Hight or low from the bullseye. Don’t worry about wind yet. Just elevation. So if your bullet impact is say 6” low you will add 1 MOA or 4 clicks. This method will save you a ton of frustration and a bit of money too. Now once you have your bullet impacts on the bullseye. Adjust your FPS in your rangefinder till it matches your elevation turret on your scope. Don’t forget your BR2 Rangefinder is all ready calculating air pressure and your angle/cosine ( up and down hill. ) that is why the above method works so well. [/QUOTE]
