[QUOTE="Broz, post: 552808, member: 7503"] No not in my brass, I use wby brass for the 30-378's. In the 300 win I am using Lapua brass which is no longer produced. I think if you get to 77 gr safely in the 300 with WW or RP brass you will still have a little room depending on seating depth for your rifle. But if you use RWS brass you will probably see pressure at 75 gr due to the lower case capacity. If you use RWS brass and have a short throated rifle or short mag box, then you may see a compressed load for the 300. I would start about .020" off the lans and get the charge then fine tune with depths. Jeff [/QUOTE]
