Hi MD, so this leads me to my question. I load a 142 ABLR in my CM. My A7 allows me to load them very long and still not touch the lands while being close to the full magazine length and I get 3/4" or better groups. If I am loading too long how do I know? I could blindly follow the Nosler OAL published or what you suggest but does it really matter in this instance. Obviously, I'm too wrapped around the axle on this. Mac
