Good stuff here. Has me thinking a 260 Rem might be fun to try! Regarding Sciroccos, I've only shot them in 338 Cal, but found they were very finicky regarding seating depth and were a tad bit slower than other bullets of similar weight once I hit pressure. Very long bearing surface causing higher pressure? I don't know. I only include that here so maybe someone else can explain it to me. Once I found the right seating depth they really shot well though. They made a swing from not good at all to the tightest groups. Very tough bullet too.
