I have a good friend that just bought ADG brass for his 300WM. He's going to be working up loads with 180 TTSXs. Does anyone use these 2 components together? He's been using IMR4350 with 180 partitions, so I think that's the powder he'll be using. Any input would be appreciated. I use ADG for my 7saum and I know they recommend backing off 10% due to it being thicker.
