From the $$ on that site for Primers, powder, bullets....Just as cheap to shoot factory. At least in .38, .357 and .40. I have plenty of all the componets PLUS about 800 factory loads for my guns.
I had 200 Large Pistol Primers I got in a box at yard sale. I dont use them, so I sold them to a guy at the LGS looking for $6. I figure what goes around comes around...And so far it has....
I still have 700 large rifle Magnum primers I got in the same yard sale box. Those I can use for the .308s if I have to. I figure Im good for the rest of the year on all my ammo and reloading supplies. But I continue to pick up things if they are reasonable.
