I concur that loading 115 ball ammo is a financial wash, especially if you don't already have the brass, and this is ignoring all the reloading equipment.Ive considered reloading 9mm, but its not cost effective as just buying a loaded box for target shooting.
However, if you want to load Sierra 125gr JHP or 147gr HST sub rounds then you can save a ton of money over what those retail for...especially the subs. Blue collar reloading is the best place I have found for buying projectiles.
