Mike - we all load fairly tight combinations that load the same for the 80th shot, as they do for the first.

My deepest rifled guns have .012" rifling. They do not require any wiping at any time for an entire day's shooting. When you're shooting instead of wiping, that can be a lot of shooting.

My bro has a couple Rice and Getz barrels with .016" rifling. They-too shoot cleanly, with never needing wiping as no fouling builds up.

We all use balls that are pure lead and usually .005" smaller than the bore PLUS a .020" to .030" lubed patch. There is no buildup of fouling while shooting and loading is easily accomplished with the rifle's hickory rod, no matter the calibre.

We will sometimes use a range rod, just to eliminate having to remove the rifle's rod and replace it, every shot.
