The reticles are not caliber specific. We do not offer it with caliber specific features.
there is no specific setting for 300prc , however, they do give a list of calibers and have to find in range of what you have , I have a 7mm08 and closest to that is 308 and adjust accordingly had it on this rifle for 22 yrs and no issues. great thing about this system is can take it of and place on another set it and then revert back to original and it's still typically sighted in. but I have one of the early models when it was still called Leatherwood and not the hi-lux so I can't be 100% sure on the updated version
