Agreed. I was actually surprised to find that .44 spl / cowboy .44 mag is way more expensive than full power .44 Mag loads are. And full power .44 mag isn't cheap! Pretty much anything that isn't a .mil surplus round can be reloaded cheaper.
This has been the case for awhile now and I really don't understand it. Usually a product's profit margin (markup after raw material, labor and overhead) is directly proportional to it's sales volume. I know darn good and well that with the popularity of SASS that the big bore calibers used in CAS outsell the standard loadings several times over. Or at least they used to. But the cost of that type ammo is just not realistic, if one is a dedicated cowboy action shooter he'd need to be a billionaire not to reload.
