The principal .32 Caliber cartridges I load for are .32-20, .32 S&W Long, .32 H&R Magnum, .32 ACP, and infrequently .32 S&W. I have a mould for the .32 S&W but rarely use it as that cartridge is only used a few rounds a year. The .32 ACP is another matter, but I only use commercial FMJ bullets in it.
For the first three cartridges I only use two different cast bullets.
The bullets I use are Lyman 3118 and 31133. Both are approximately 115 grains. Basically the 31133 is simply a gas checked 3118 as I assume you know. For all three cartridges, and several guns I have in these calibers I size all my bullets .315", which works well for all my guns. I have a Marlin classic Model 1894 in .32-20, a S&W Model 30, and several Colt and S&W revolvers in .32-20. My .32 H&Rs are a S&W 631 4" and a Ruger SP101 4"
The reason for the two bullets begins with .32-20 as original factory ammunition was loaded with bullets from 100 to 125 grains, and these two fit right in the middle and work well for all three cartridges. Unless you have a thing about wanting bullets of a specific weight I would suggest simply buying a 3118 mould and not worry about commercial cast bullets. All my bullets are lubed with Saeco Green that does a better job in every respect than any of the highly touted "boutique" brands that cost $5 and more per stick. I make my own Saeco so cost is less than $1 per stick.
Using these bullets most of my guns, including the revolvers, will shoot under 4 "/100 yards! The Ruger will do minute of pop can at that distance. It shoots like a rifle with heavy loads that run nearly 1,400 FPS! The .32 H&R can be a true Magnum, but just not with the wimpy Federal factory loadings.

Most of my ammunition is loaded with Unique. Naturally the heavy .32 H&R loads are not Unique. They do not get used in the 631 either.
