I would tell you to stay away from Golden Bear (copper washed steel case) I purchased 1000 rounds before ammo prices started going up a few years ago and have found that it is crap ammo. I average 3 "non ignition" of the primer out of every 50 rounds or so. My primer strikes look good, just no bang.
Centerfire has tula ammo in 223 or 762x39 for 179.50, delivered for 195.17 Centerfiresystems.com
another question
is there any differance between the HP and FMJ rounds? just havent seen much ballistic info on these cheaper rounds
I'm not sure what caliber you're looking at, but all of my AR's have functioned fine with hollow points.
On the other hand all of my AK's are finicky with hollow points, and big time unrealiable with soft points.
