I want to see how the groups open up after a few groups in somewhat rapid succession. Note that I'm talking about just an afternoon of shooting and NOT full auto-esque mag dumps. Just normally shooting of a few boxes of ammo at the range type thing. From what I hear that's why most scrap the factory barrel in favor of better offerings from LRI. They shoot wonderful groups but things open up a noticeable amount after some prolonged trigger time. I hope I'm wrong as I've been waiting for a killer deal on a 6.5CM factory RPR but from what I keep reading I may just pop for a killer deal on whatever I can get my hands on (likely 308) and then swap out the barrel for what I want. If they did something different to the factory barrels that makes them viable that saves me some coin.
