The reloading manuals while they provide useful data for each cartridge and a certain bullet combination, they also provide very useful info such as do's and don't's, history of each cartridge, ballistic tables and trouble shooting info.
The data has changed over the years and even the older manuals can provide comparison data to build from as new bullets are designed.
I try to maintain the PFD files from the powder manufactures and reference there on line info frequently. BTW I have handloaded since late 1970's and 10mm since March 1990, and still learn better ways of doing things and teaching others too.
Remember Hollow Point designs are longer than the same weight FMJ, JSP so they occupy more case capacity, also the solid copper designs are way longer for their given weights because copper is lighter than lead core.
