There have been some discussions here lately about not using loading data for one bullet when using a different bullet, other things being equal. I can agree with that to a point, but I think most data says that in most cases bullets of the same construction act very similar when loaded with the same powder. I am talking about grouping handgun bullets into 3 major groups: copper jacket, copper plated and cast lead.
Can anyone find current published data for copper jacketed bullets in handgun calibers that does not follow reasonable general guidelines. It seems the powder manufactures only pick one type of bullet in a weight class for testing. I have yet to see current data that shows very different max. loads for different bullets, with the same weight with the same powder.
Now if I go back to some of the old Lee data I can find considerable differences between max. loads for different bullets, but I don't take these to the bank as they are a collection of data from years past and some things have changed. I also don't know where the data came from.
So what do you have for jacketed bullets, including but not limited to, REM JHP/JSP, HDY XTP, SIE JHP, NOS JHP, SPR JHP, SPR UCHP (uni-core), SPR GDHP (gold dot), MAG JSP/JHP, WIN JHP/JSP.
Any of these bullets act differently?? For instance I have been loading REM JSPs and XTPs and SIE Sports Master JHP in 44mag close to max and have not noticed any major difference. I wish I had a chronograph. Reloading is a science and we should be able to identify and quantify these differences. ...And of course, Let's Be Safe Out There.
