Casting
Preheat your glue gun.
Lubricate your mold cavities with the q-tip. Vegetable oil works fine, This may need to be reapplied occasionally. Some people use cooking spay like PAM. This seems to last longer, but veg. oil is easier to remove from my molds. This is only really important if you also intent to cast lead.
Shoot the first cavity full of glue. Do this as quickly and smoothly as possible. Leave a heaping pool of glue on the sprue plate. Much of this material will be drawn down as the glue sets. Failure to provide this extra material will result in an inclusion in the base of your bullet.
Wait a few seconds or your glue gun to catch up. This is especially required for the cheaper ones.
Shoot the second cavity same as the first.
After 60-90 seconds, depending on the size of you mold, open your sprue plates and remove your gloobits. Your first couple might be a little ugly for the cold mold and excess lube, but don't let that stop you.
Remove the excess glue from the sprue plate and mold some more. I haven't used a mold that didn't produce perfect gloobits on the second or third cast.
Loading:
Deprime fired case.
Open flash hole with .125 bit. This is important to keep primers from backing out.
Prime. Small rifle primers can be substituted for small pistol. Some people use large rifle instead of large pistol, but to do this properly requires modifying the primer pocket.
Insert the gloobit. I have no trouble doing this by hand. You may want to push the projectile as far into the case as possible when loading for revolvers.
Firing
Lubricate your barrel.
Load and fire as normal. A soft backstop such as scrap carpet will aid in recover of reusable gloobits.
