Hornady. They rebuilt my 366 press without charge. I don't know if that is, or was, their usual policy, but I'm now a dedicated customer. Bullets, dies, everything.

Carlson's choke installation. Very fair price, 7 day turn a round, exactly as ordered, and I dealt with personable people.

Smith & Wesson. I bulged a .45 barrel by shooting FMJ after lead. My fault. They replaced the barrel without charge and paid shipping both ways. Years later the striker on a 9mm pistol broke. They replaced the entire slide with all new parts. Paid shipping both ways again.

Vortex. I called about replacing scope caps on a red dot. Three days later a package arrived with the caps without charge.

A couple of these are small, but a few are kind of big to me. I remember those who have helped me.
