I'm using ADG from Alpine Precision - seems good so far and Cam is great to deal with. Started using WRE large magnum primers as I could get my hands on them. They were very tight fitting to the point that it was pretty tough to seat them flush. Managed to get a box of Fed 215s when the last shipment came in and they seat much easier.
I see Workshop Innovation now has Peterson brass in stock too, which gets good reviews.
