With matches and practice, I'm shooting 1000 to 1200 pistol rounds a month, and have since 93 when I got into action pistol. I'm shooting less than 1500 rounds of 5.56 a year these days so most of my reloading is pistol. I have multiple die sets in every caliber I reload, so it's hard to tell how many rounds have been loaded with any one set. The ones with the most volume are the 9mm Lee dies in a Dillon tool head, second would be the .40 Dillon dies also in a Dillon tool head. Although I have been reloading since the 60s, before 93 I loaded probably less than 2000 rounds a year of pistol, rifle, and revolver combined. Although I've broken my share of decapping pins, to my knowledge I've never worn out a die. I run clean brass through my presses and gauge or chamber check every round that comes off my presses, so guess I'll know when it happens. Makes sense that the steel rifle dies would wear quicker than carbide pistol dies.
