[QUOTE="GoosePilot, post: 1750952, member: 104513"] Ok thanks. I think I'm getting a feel for reading primers in this LAW m704 action. I dont get ejector marks or swipes. It doesnt take much powder at all and I get cratering and then it gradually increases. When i have heavy bolt lift, I get a secondary ring around the crater, the crater rim is more pronounced, and the primer has some flattening on edge. At this point, the brass measures +.0005 base to shoulder, also on the wall/shoulder diameter, and sometimes at the base/web diameter. If i back off of that a little more than 2g, then there is zero bolt lift, no secondary ring around crater, and crater is less pronounced, the case is no more stretched than at lower powder charges.
