Hi all. I need some ballistic help from some of you much more knowledgeable and experienced marksmen. I have a custom 7mm rem mag with a Leupold 4.5 x 14 x 40mm VX-III scope with the Boone and Crockett (B&C) reticle. I have been shooting the gun well for a couple years, mostly under 300yds shots on game, but I’d like to try to take this setup to the next level and get comfortable in the 300-500yd or 600yd range. At the 300 and 400 yard range using the corresponding hatch marks in the reticle using the large triangle, I am a bit off 6”+. I’m sure some is shooter error but I’d like to take this step by step from the start since the load data in the cartridge Leupold shows doesn’t match what I’m shooting. Closest is the 150gr 3050fps in Group A (large triangle with a 200yd zero). Here’s Leupold’s manual for its Ballistic Aiming System… http://www.leupold.com/wp-content/uploads/2014/09/BAS_Inst_Manual.pdf I’m shooting a 160gr Accubond bullet and I’m using a 200yd zero. I do not know my fps, but I have a chrono on order and will measure that as soon as I get it. Once I have my fps and know my bullet’s BC, I’d like to build a POI chart for each of the hatch marks in the reticle based on the scope set at specific power settings. I’ve read some old posts on this subject and they reference a tool named “reticle tool” in a program named “Exbals”. I found the program but can no longer purchase it and emails to the company/developer have gone unanswered. I’m hoping folks on this site can help walk me through this process of how to determine exact POI/MOA figures for each hatch mark in the reticle for my load at any given power setting. Any and all help would be greatly appreciated!! Thank you.
