In looking at .223Rem and Hornady 55gr FMJBT #2267 bullet, Hodgdon's website data shows Varget achieving 3,384ft/s with a charge of 27.5grs. Their "standard" load shows 3,174ft/sec with 25.5grs of Varget. I understand that the best grouping will most likely fall somewhere between these two charge levels. I also understand that most will do a ladder test to zero in on the ideal charge.
Is the "Sweet Spot" always something between the "standard/maximum" powder load, or is it a velocity driven thing for a given bullet weight and shape? In other words, if I found the sweet spot with the best grouping at a given velocity from this given gun, could I use a different powder with that same projectile to hit the same velocity and expect close to the same results?
