I've done it with a bone stock Tikka 6.5CM and American gunners. A lot has changed in 3 years, thousands and thousands of 6.5 PRC shots being just some of them. When Mud said that, he felt he was right. However, as most comments in social media don't age well, this one is no different. Since then, we have more shooters running the PRC than we do the 6.5x284. How do I know? Availability. It's simple. Will this argument ever die? Doubtful. Someone resurrected a 3 year old thread… that's where we are as a people I guess.
Shoot what you want, don't be stupid and remember that unless you're married to it, its opinion doesn't matter
ps, my intro to LR was a 6.5x284. Don't have one anymore, but I do own a really nice 6.5PRC
