Just went out today and started a load development for Komifornia regulations. 7mm rem.mag ,Rem 700 in a magpul hunter stock. About the only powder I could find local or online was reloader 25 so that's what I went with. It is going to be a combo hunting /1000 yard steel play gun. With that said I'm going with Barnes 145gr LRX and 150gn. Sierra hpbt matchking. I loaded 1 round each from min to max , 66-73 grains to find the max loads for my rifle with both bullets. With the Sierra matchkings I found a good node at the 71-72-73 range 3100 fps and didn't run into pressure signs. With the Barnes LRX I have a node at 70-71 range with 3200 fps . I did have pressure signs at the max load of 73gn. Now to start dialing in my powder charges! Of interest the Barnes LRX were consistently 100fps or so faster than the Sierra with the same powder charge.
