I finally got to cutting open and weighing a couple of RST shells that I have. Both are 1oz lites. 6 and 7 shot.
Actual shot weight was .982 and 1.017 oz.
Powder measured in at 18.6 and 18.8 grains.
The other thread referenced mentioned using 20 grains and achieving 1,220 fps.
I know these factory RST loads are rated at 1,175 fps. if I remember correctly. So I am sure the additional grain or so of powder makes for the increased velocity. I am going to check out the local store by me that is known for having a lot of reloading supplies for very reasonable prices. Will have to see what kinds of powders they have. I doubt if they have the wads I need, but we will see.
