[QUOTE="Stgraves260, post: 1981390, member: 19988"] I put that chart up for someone who was using a rangefinder that did not calculate for cosine. I thank someone was using a Vortex 5000 something. I read about it a little and it only adjust for cosine out to 800 yards. I have a first gen G7 and a Vectronix Rangefinder. Electronics fail so I got a back up. I use my mil dot master sometimes just so I stay fresh with it. I’m looking in to the new Kestrel 5700x. That and the Garmin 701 Foretrex. I also still like to use my Knights Armament ballistics calculator. It’s fast and easy when only going out to 2000 yards. When I made my 2300 yard shot that’s what I used. I have data in my sniper log that takes me a bit further than my electronics. So I had to pull that out also. All my electronics were failing at times so I had to go old school and use my calcform. I was in Brawley California visiting family and friends. We were shooting in the dessert. It was like 115-120 degrees out there. Had to set the rangefinders in the truck a few times and let them cool off. I was really surprised how well the G7 worked for the price. Overall I thank it held up pretty good. Some sand got into the buttons so I cleaned it off with a little bit of rubbing alcohol and everything was back to normal. Oh well, wishing you and the family good health during this pandemic. Good luck on your hunts this year. [/QUOTE]
