I'm still debating on getting in to reloading, but I always see so many varying costs for what you can reload a certain caliber for. Sometimes they seem like they are almost too low to be true.
Stop debating and get started now because you will always find many varying costs depending on who you ask and what/how they buy. That is one of the great things about reloading. As a reloader, you have much control on cost by your selection on components.
An example on varying cost is on the bullets. The price can range from the low end for those who casts their own all the way to the high end for those use buy the premium jacketed options. Buying in bulk and watching shipping rates makes a huge difference also.
Many have access to free range brass. Some buy their brass, whether it's once fired in bulk or new brass.
I have often times found good deals at gunshows on powder and primers. Some probably have ordered themselves in smaller quantities where the haz mat inflates the cost quickly.
