I've run around 1,200 of the 140gr Nos CCs through my RPR with good results. They shoot quite well out of that rifle, the oal is such that I'm currently loading to 2.78" and am 20 thou off the lands. I use the Litz G7 BC of .281 to get my starting come ups and things matched up quite well. There are slicker fancier bullets out there, but for me the CCs are a killer value given how they shoot. I picked up my last order of 1k from Shooters Pro Shop for $192 shipped... Hard to beat that.
