So, I am very new to this very cool newtonian physics based world of precision long range shooting… lots of reading, and YouTube university! So I purchased a Browning LH x- bolt Hell’s Canyon 6.5 PRC, 26” barrel rifle and 20 MOA P. Rail and the Khales k525i… - so I could use help with the mounting ring system. There are many choices. Best ballistic programs to download and guidance on some of the best schools to attend….
