There have been more changes in load data recently than I have seen in the last few decades with common favorites from the popular powder brands. Essentially, all my manuals and data up to about ten years ago have some pretty big changes in load data compared to what the powder manufacturer's are publishing today.
For example, check any older reference for an AA#5 load in 9mm 115 FMJ (or most 9mm loads) versus what Accurate shows online at their website now and you'll see almost an entire grain weight in difference between old and new start and stop grains. They have done extensive recent in house testing in reducing the cartridge COL to get speeds and pressure to run with the old loads in reduced lengths and charge weights.
Whatever powder your using to load with, at least review current load data straight from the powder company these days.
