Wildcats are non-commercially made cartridges. Please do not attempt this until you have aquired a lot reloading experience. It keeps you out from under your spouses feet in the house. You have a lot of chances to go from scaring yourself bad enough to cause a changing of your drawers to destroying your house. Wear eye and ear protection.
Prescription glasses are okay, as long as they are shatter resistant.
Keep distractions to a minimum. If you are using a single stage, do each step to the lot you are reloading before moving on to the next step. Follow all recipes exactly. Never improvise or guess about the loading data. Read the instruction manual for each piece of equipment you have,and keep it handy for later reference.
