Cleanest/best .45 Acp

[GunsNotPuns]

While the Sig Scorpion demands only the very best unicorn horn dusted .45ACP ammunition but you'll find that American Eagle works just fine too.

The "NT" marked ammo from some makers is often very clean. Forgot which in particular is the best.
Some brands eject looking better than new unused brass.

yup. Winchester NT. Not a speck of carbon in the base of a fire shell...
