I've polished the feed ramps and rail on all my guns. While I found it really made a difference on one of them, I'm wondering how it really helps the feed ramp? After a few shots the ramp is coated with burnt powder anyhow. How does a "mirror" finish help after the first shot?:confused:

It doesn't.

When we talk about "polishing" a ramp, we really mean "Smooth" a ramp.
The idea is to SMOOTH any rough surfaces that might catch a bullet nose.

The trouble is, we say "polish" as in "smooth" but people HEAR "Like a mirror".
When you try for a mirror polish, too much metal gets removed, angles and contours get changed, and sometimes the gun is LESS reliable, even ruined.

So, why is it that all custom guns have mirror polished ramps?
Simple. The customer pays us for a "polished feed ramp" and when he gets the gun back with a smooth, but not shiny ramp, he figures we ripped him off by charging for something we didn't do.
The result is, we have to give ramps a bright, mirror-like shine to satisfy the customer.

A mirror bright feed ramp offers NO, ZERO advantage over a properly smoothed ramp.
SMOOTH is good, Mirror-like usually isn't.
