[QUOTE="excaliber, post: 1020186, member: 86034"] My gun is a Rem 700 bdl 300 WM made for Cabelas with a 26" fluted barrel and a Leupold 4.5x14x40 CDS scope mounted on it. It really likes the Federal 180 gr speer SP loads at factory specs of 2960fps. I have no chrono yet. It did not like the Doubletap loaded Accubond's rated at 3050 fps at all. I want to start with the Accubond's(180gr) I'm just starting to get my supplies together to reload my 300 Win Mag. This is going to be a hunting round not a long distance precision target load. I'd like to be able to shoot out to 600 yards for practice with most of my hunting shots being much, much shorter in distance. I finally have Winchester brass. I have Fed 215 LM Primers and Nosler Accubonds(180 gr) I'm still searching for some H4831sc or RL22 as I'd like to start there. It's hard to find data with the components I have. The closest seems to be from Winchester as it specs Win brass and the Nosler Etip bullet. Shown below. Are these conservative max loadings as they do not seem much faster than factory loadings? I do see it's out of a 24" barrel. I see most people's reloads are faster than this. I'll start low and work up but I was wondering if the data below is on the conservative side. If there is some more complete data for the Accubond with Win brass please let me know.
