Bear Creek Supply has been making superior coated bullets since 1991. Check out the details: https://www.bearcreeksupplybullets.com/aboutourbullets
Their polymer/moly coating makes a measurable difference in friction reduction as the bullet passes through the barrel, and after hundreds of rounds there is no lead buildup. They also seem to feed better in my rifles and keep everything cleaner and lead-free when reloading.
They have some great quantity discounts and will ship for free if you order over $130 of bullets. I've been to their manufacturing facility, amazing Made-in- the-USA operation with many custom built machines.
