Copper inhibitors in powder

[Albert]

Do the powders that say they have an additive that reduces copper build up in the barrel really work?
And of those that do work, which ones are being used in long range f-class open? Thanks

I shoot almost all of Alliant powders, RL26, RL23, Imr8133, N570... I do not think any of these powders are miracle workers.

I am a velocity hog! Velocity smears copper, fact of life. And the more fire cracking you have the more copper it collects to fill the cracks, not sure how a simple powder ingredient can EVER solve this.

Today, it's a marketing gimmick. Copper inhibitors have been in powder for decades, at least back to WW2.

Like the CFE's ?
