Yes. That is an old practice actually, not nearly as popular in this day of readily cheap ammunition. It has been done with #1, 0, and 00 buck, and in other calibers such as the popular .303 British. You neck seat, put a dab of lube on them, and then load with something like 3.0 grains of Bullseye, WW231, etc. To ensure uniform velocities, most guys raise the rifle just before firing to position the powder back by the primer. The first time you try such loads, you will probably be quite surprised with their accuracy. Very cheap, and a fun load for practice with your hunting rifle. You can also try and improve your results by using an 0 or 00 buckshot, placing it in a gas check, and then running it through a sizing die, followed by the same kind of powder charge.
Fun little loads, and it is often a lot less aggravation to simply buy a bag of Hornady buckshot than start the lead pot up and get the moulds warming...
