I'm sorry not much load development with 180's and 7saum because a decided to try 162's since I had a bunch. I will post some pics with the 180's and 28 nosler barrel later. Real busy right now. Both barrels are 24"s + brake.
I managed to find one 200 yrs target with the 7saum in the beginning. Most are from 28 nosler barrel will post soon. The gun will shoot better then me I'm not that great of a shot.
