I really like their brass. I ran a bunch of their 243 and some of the 6.5 Creedmoor SR. I did a mini writeup on here about the 6.5 after weighing and measuring all 250 pieces and being blown away by the fact that it's twice as consistent as Lapua is. I also like that it has a standard size flash hole which helps prevent hang fires in cold climates. My rule of thumb now is if Starline makes it, I run it.
Just ordered 200 pieces of their 6mm Creedmoor SR brass yesterday for my Q.
