One other thing that you'll figure out pretty quickly. Fast powders, like Bullseye, are great for low recoil and accurate rounds. However, most of them tend to be very low volume powders. That's both good and bad. The good news is that a pound of powder will make more rounds because the charge weight is smaller.
On the other hand, those small charges do pose some risks, especially for a new loader. If the charge is small, it's not easy to see a double charge. If it's small and your brass isn't sorted/consistent and/or your bullet weight isn't very tight, you cannot meaningfully use total cartridge weight as a QC measure against double-charges or squib/no-charges.
Once you've reloaded for a while and have good habits and a proven track record of never screwing up, then a small volume powder can be great for the reasons I listed above. Until then, you will need to be EXTREMELY careful. You need to be careful regardless of what powder you're using, but with a low-volume powder, you're not going to get any visually-apparent warning that you're building a grenade or a squib.
