Hi Guys, I have a few questions and am hoping for a little help. I am getting back into reloading after being out of it for about 15 years due to moving around the country. I have set up my reloading bench in my new 'retirement shop', and have reloaded for my 10mm first, and it is a good load using a new powder to me, the 800x (but it measures like crap).
In all of my old stuff, along with what I inherited from my father in law, I have a bunch of Unique, which use to be one of my favorite pistol reloading powders. Since my reloading books were so old, and didn't even have a 10mil or 40 listed in them, I had to buy new books. Well the new books are showing a little difference in loads for 45ACP compared to my old books. To give you an idea of the age of the powder, one is a 4lb canister, was $21.60 and is lot UN011. The other canister is a 1lb'r, $6.95 and has lot UN 099 on the bottom. As far as storage of the old powder, it was always in a dry, cool, dark place, boxed up. No change in look, feel or smell.
SO, my question is, are there differences in the old load charts vs new charts due to differences in the make up of the newer powder? It shows using just a little more using the older powder vs the newer. I know I will have to go on the conservative side to begin with, so am thinking about right at 6.0 grains pushing a 230 grain FMJ-RN and using just a Large Primer vs Magnum.
