I was doing some research on the difference between chrome lined barrels and Melonite. If you want to read something interesting check out the friction coefficient between the two. In the following attachment they show that the friction difference is tremendous with Melonite winning by a mile. It is very much a technical read but after reading posts by the people in this forum I feel that everyone will understand it.
Wear Resistant Coating, QPQ, Melonite, California

Have a wonderful Day
p.s. While I am recovering from my 6th surgery in 2 years I have a lot of time!!!!
