I’m a reloader who has never really dived deeper than producing accurate hunting ammo .
I have a question to ask about the velocity - accuracy relationship of loads .
For example
You have a chosen load you have developed that is accurate and safe with brand X powder/projectile/primer/brass
You chronograph that load and get it’s average speed , lets say 2700fps for argument’s sake.
You then change powders to brand Y but change nothing else ( same seating depth ) and find a powder charge weight with that new powder that duplicates the 2700fps average.
Will that load match the first load in regards to accuracy/ performance or will there be a difference?
Does the burn characteristics of a powder / case fill percentage / pressure characteristics etc effect the accuracy / barrel harmonics of the load even if the projectile is leaving the muzzle at the exact same velocity ?
Just thought I’d ask those who are way more knowledgeable than me on these subjects.
