Barrel ?

[Steve Anderson]

I'm usually in the back of the class acting up so I might have missed this. So forgive me. It seems that good shooting cast bullet barrels and good shooting jacketed bullet barrels are not one in the same. The benchrest jacketed bullet boys appear to favor different barrel makers over the cast bullet boys. Assuming I'm correct, why is that? Do cast bullets work better with more friction in a barrel. Is it about the barrel dimensions?
