Varget Powder, Start=25gr, Max=27.0gr.

Hornady Data. 223 Rem, 60gr Hornady V-Max, 2.250 OAL.
Varget Powder, Start=21.7gr, Max=24.9gr.

It is not uncommon to find a situation like this where the Max charge in one manual is less than the "Start" charge in another. Same bullet, same OAL, same powder, yet completely different results.

As I said, staying within book data is often time difficult if not impossible. Quickload is certainly not perfect, but neither are the loading manuals.
Where exp comes in. When I am going to a new bullet/powder or calibner combo, I use avg book data & work up. Using a chrono, comparing vel to book data, modififed for bbl length of course, it's a safe way to work up loads w/ no guessing involved. Like data manuals, LQ is another good tool, but not to be trusted as the final word.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
