I bought a used Ruger Hawkeye in .223Rem at Cabelas. The rifle is in really good condition. Looks like it has hardly been shot.
Got it home and ran a borescope through it. I am very impressed with how smooth the Ruger barrel is! Probably the smoothest factory barrel I have ever seen.
However, the chamber has zero freebore. As in zip, nada, nothing, 0.000".

No problem. Now I have an excuse to buy a Unithroater kit. My plan is to hand ream about 0.025" of freebore with the barrel on the action. I've got other rifles that I will eventually want to use the Unithroater on, as well.
I see the Unithroater reamer comes with either straight flutes or spiral flutes. What are the benefits of each flute design and which would be best for my application?
