I've had good luck with Rainiers
If you gotta have cheap, go with coated lead. Almost as cheap as fast lead, without the smoke, lube and grime.
Anyone have any luck requesting particular bullets from XTreme? They don't really have anything that will work for 300 Blackout (7.62 AK bullets are too short, flat point 308s won't chamber) and it kind of stinks paying 20c a round when there really should be cheaper alternatives out there.
