Anyone used ETR7 in 45 acp?

[JedYonkers]

$87 shipped for 4 lbs of in stock pistol powder had me looking at etr7. Says to use titegroup data, 4.5-5.5 grains. Any one worked up or ran some through a chrongraph? I've also heard it's csb 1 in a different bottle but I haven't used that either.

We have a distributer in va that sells this stuff. The guys here pretty much use this for almost all their pistol needs. One guy actually sold all his pistol powder on the forum and bought tons of this powder . Me I personally a unique, bullseye, 2400, and h110 guy but from what I hear this could replace my unique and bullseye if I wouldn't be so stubborn
