Anything you can buy in bulk could be considered, "low cost production ammo". All ammo is made to a given set of specifications, i.e., pressure levels, etc. The problem with ammo, 22LR in particular, is that some guns are more finicky than others, and may not feed or function properly due to softer bullets, variations in OAL, thicker rims, or whatever. The only way to know if your gun will feed and function normally with a brand or batch of ammo is to try it.
I'm not a huge fan of Blazer ammo, but I've shot enough of it in various calibers to know it works pretty well, and a couple of my 22 rifles really dote on the stuff. When I tested the Blazer Brass ammo in 40 S&W, it showed a standard deviation of FIVE fps. Hard to beat that kind of consistency! 8)
