I have both. I've not read much on barrel life for the PRC but the 6.5-284 is a barrel burner, my experience was about 1000 rounds and I replaced. For the average hunter the barrel life is probably not a big deal but for a bench shooter, competitive shooter, or recreational shooter that like to send numerous rounds down range it may be a deciding factor. Both of mine are extremely accurate and I believe the PRC will send the new heavier bullets down range with more velocity but I've not experimented as of yet. Good luck with your choice.
