I've used Remington, PMC and Winchester, all of which are on the cheaper end of the scale as far as quaality goes and I have'nt had any problems yet. The brass will need to be trimmed at least once every three reloads anyway and if your really into it you'll trim every time. I usually get between 10 to 15 reloads before I start seeing split cases, etc. I full length size every third reload.
