Re: 300 wm reload
I work with a lot of 300 wins, many Senderos, and a lot of Bergers that we shoot well pat 1000 yards. But I prefer the larger bullets. If it were me I would load the 215 Berger Hybrids and start with 74 gr of H-1000 (WW or RP brass) (with RWS brass start at 72 gr.) and a CCI 250. or Fed 215 M. I found the seating depth of .-040" off the lands to work very well. If you can't find the 215's the try the 210's with this same load. I have taken these loads past a mile several times.
