Used bore with minimal wear, graze breaker or berry bush hone= cast rings.

Fresh straight bore properly honed for moly rings= instant break in.

Straight bore with proper finish= Chrome rings. For heavy duty, constant heat/load. Take longer to break in. Will last longer under the right conditions. No tolerance for dirty air/oil.
