I've got brass from starline, federal, winchester, remington and pmc. Can't say one is better than the other, all have been reloaded 8 times or so. If I was to just go and buy 1000 pieces of new brass, you can't beat starlines price.
Just for punching holes in paper, I buy commercial cast bullets from Mid Kansas bullets or Berry's plated bullets.. These I favor above cast because they seem to preform well in all my guns. Ordering Remington Jacketed bullets are a great price for this style bullet.
Berry's delivers free for orders above 25 dollars. I think Starlines prices are with postage included.
Mostly I've ordered from MidwayUSA or GRAFS.com, I've not had any problems with either of them.
