I can almost always find load data for a particular size and weight of bullet in one particular type, such as a JHP, but I can't always find load data in that same weight for any other type, such as an FMJ. Powder charges for these two bullets would likely be close enough to interchange between bullet types, but because of the difference in nose shape, the OAL is likely to be significantly different. I'm speaking of average pistol loads.
I know that if you know two of the three parameters for a particular bullet, OAL, seating depth, and bullet length, you can always calculate the third. So if I just calculate the bullet seating depth of the JHP, based on OAL and bullet length, I can apply that seating depth and the bullet length of the FMJ bullet, and come up with an acceptable OAL for the FMJ load.
The OAL for the particular load and bullet is always in the load data. But the bullet length never is. If you don't have an example of the specific bullet mentioned in the load data, it's impossible to know the length of that bullet, unless you can contact the bullet maker and ask.
Is there any other fairly reliable method of figuring OAL on a bullet like this?
