Most of my pistol brass is range brass, some I bought, like .32 ACP, but most I picked up, including .380, 9MM, .38 Spl, .357 Mag, .40 S&W, .44 Mag, .45 Colt, .45 ACP. I bought my .32 Long, .32 Mag, .32-20, .400 Corbon, & .41 Mag.
90% of my .223 is range brass I picked up, and I would be OK with it all being range brass. When you have a lot, been picking it up for decades, you can sort out a pretty nice batch if you need to.
I have a lot of .308 range brass, but bought my "match" (Lapua) .308 brass. My .30-30 brass is range brass, I bought my .35 Remington, my .30-06 is range brass, I bought my .458 Win Mag. I bought my .22 Hornet brass, my .222 brass (No longer have the gun), and my .222 Mag brass.
I bought my 6 Dasher brass naturally. I bought my Hornady 6 Creed brass (Gave the rifle to my nephew to shoot PRS with, and so far he's using factory ammo). I have 100+ 6.5 Creed brass and sorted out 50+ Hornady cases to start loading for my older brother one of these days, and he's saving his factory Hornady brass.
I shoot a lot more pistol calibers than rifle calibers. I tend to be more serious with rifle (Have a purpose), where I shoot pistols for fun.
