What's the general consensus around bullet setback?

Paul Harrell actually has an excellent presentation on this topic on YouTube - a good rule of thumb is especially if you’re familiar with what your ammo looks like, if you can see a difference in the round without comparing it to anything (ex. Un chamber the round “oh damn that’s short”) it’s time to change that round out. If the round has a cannelure the case mouth setting on the top or bottom side may not be an issue but if you notice the cannelure is well above or below the case mouth I wouldn’t shoot it. With most factory loads with the exception of something with an animal on the box you’re probably ok with a little setback but if you aren’t sure another member mentioned something along the lines of “the accident isn’t worth .70 cents” and that’s always a good safety plan

Yeah this one was (obviously) noticeable without comparison. No way I was shooting that little bastard.

Would this speed things up?

My initial reaction was, how perfect. But then I realized this gauge is for case length. Setback is referring to overall cartridge length, case plus bullet. Plus, different bullet types have different OAL, so you would have to make a gauge for your exact carry bullets to be able to use it as a guide for setback.
