You are rarely going to find data using the exact components. So you have to learn to extrapolate data. As you have already learned, not all bullets are the same. So the safe bet is to use average starting, or a bit higher, for bullets that are the most like what you are loading. Load in 0.1gr increments & shoot them in order, noting reliabilty, accuracy & any pressure signs (low or high). Load no more than 10rds (I hate pulling bullets), approach any max data w/ caution. Load to the longest OAL that YOUR gun will function w/. Use your bbl & a dummy round to determine proper OAL.

"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".
