BDC (Ballistic Drop Compensating) Reticles are fast, simple and extremely popular. The hashmarks are based on a general ballistics curve most popular big game calibers follow pretty close out to 600 yards. But what if you want to know exactly where the hashmarks line up for your rifle and the load you’re pushing through it?  What if you have a cartridge that falls outside of the “general ballistics curve”? Good questions! Jim and Mark sit down with Ryan Muckenhirn to chat through “Truing your BDC Reticle” for optimum accuracy!
