If it's just plain ol' FMJ for range ammo, there's no benefit...buy the cheap stuff and shoot more.
Although, it's likely the cheap stuff is steel-cased Russian import; now, there's some folks that will tell you that it will: damage your gun, be unreliable, be dirty, cause global warming, insult your mother, and kick your dog. The folks who tell you this basically don't know what they're talking about.
Pretty much the only downfall of steel-cased ammo is that it's not reloadable (well, it can be, but it's a pain), and some ranges won't let you use it.
