I've purchased some different calibers and had only one bag that needed work.
Two bags of 243 Win needed the mouths cleaned up. I took down to 2.035" and started over. No problems. I like the brass. Usually use WW but have switched to Nosler on .223 Rem, .243 Win, 270WSM and 300WSM.
The only problem I've had is prompt shipping. I ordered some Whelen brass on 11/29/14 and I just got a Fedex notice that it was ready for pick up to ship on 12/3/14. It took 4 days for SPS to notify Fedex it was ready, Oh and it won't arrive till 12/10/14 that's a total of 11 days after ordering on line. It didn't take that long for the stock I bought from Eric to get here by UPS ground. Glad I didn't need the brass for a hunting trip.
Sorry for the rant I know it's that time of the year and things take longer to ship and as soon as SPS list seconds that are rare they get mobbed with orders.
I've got the 2nd brass in several different calibers/cases. Now and then a mouth will be a tiny bit flattened, but that's the only problem I've identified. The blemishes I've been able to spot are cosmetic only.
