Bullet setback is going to occur, period. You may not be able to measure it immediately, but it's there nonetheless.
Yeah, I'm sure that it may occur in some brands, or with particular lots within a brand, more often than others. But it's ALWAYS there, even with the best of brands and the best of reloads.
The question which cannot be answered with precision is "How much setback is safe?"
This is because there are a variety of factors which affect this (safety), not the least of which is the type of powder used and how much is in the cartridge.
Recognizing that setback always occurs, the solution to this is simple:
When setback is noticable, remove that round from your pistol and either dispose of it or put it aside to be used at the range the next time you go. Replace it with another one.
This should be entirely within the working budget of anyone owning a firearm, regardless of the type and expense of their carry ammunition. Unless you have faulty ammunition, this isn't going to require someone to go through a box of ammunition every week by replacing defensive carry rounds.
You do not have to mike out your chambered round for this, either. Periodically visually inspect the chambered round side-by-side with one that hasn't been chambered. If you can visually detect any setback, replace that round with another one.
