Little bit of an update!
Got to the range today and tried out a few different loads. I loaded up one round for each charge weight for each powder/bullet combo. All I was looking for was signs of pressure and I feel safe to say I didn’t see a whole lot of warning signs. Most shot around where MDWS predicted as far as velocity goes but I’m not too concerned about that right now.
I was able to shoot the 180gr XTP bullets with some success! They didn’t lock the bolt back or eject but I got them up to 2075fps. That’s as hot as I loaded them, more testing needed and I suspect my gas block moved on me is why because my 220gr Hotcors didn’t move the bolt either
Some pics of the brass. Some are out of order since they were tossed around
