Wally World is cheap no doubt, but remember, your local gun shop is supporting local business and we all know where Wally's money ends up.
I buy .45 ball from the guy and his wife up the street for two reasons. He's a small business who's doing the American Dream thing and there is something to be said for a beautiful, smart woman who's packin' heat!
I get Winchester .45 ball for about 35/100 and cheaper on the foreign brands like Sellier & Bellot, MagTech or UMC. My Para will eat anything regardless of what I feed it.
