SBT Ejector question

[Cold Spring]

I understand Chuck about worn parts, but I ask about SBT guns that were deliberately put out of time to fire the ejector a bit early as the gun is opened. One of my buds who's a long time trap shooter told me that was fairly common mod done for shooters who were heavy into reloading. 4 of 9 guns I’ve owned seem to add some credence to what he says.
