[QUOTE="JemezDave, post: 2040471, member: 108070"] Looks like the primer is cratered quite nicely(too hot). I would weigh that case compared to a hornady case or other. If the ADG case is significantly heavier that may be your problem due to reduced interior volume of the case itself. The reason I say that is on my 300 win mag I have a couple lots of "light" Norma brass. Norma also has a heavy brass listing in their load data for 300WM. The case weight difference is 215 grains for light cases and about 270 grains for heavy cases-you get the idea. There is a difference of 7 grains on the max charge using Norma 204 powder and a 200 grain Sierra MK bullet. The heavy cases use the lighter charge due to the reduced interior case volume. Make sure you're case length is in spec too. [/QUOTE]
