Just thought I would post a preview of a round I and 7mmRHB have been working on. We were looking for a true short action round that would fit standard magazine boxes but get 140 Bergers up and running and still have mild recoil without jumping to the extreme of a 6.5 WSM.
We started with Lapua 6.5-284 brass and went from there, we ended up with a perfect powder charge easily pushing 140 Bergers 3000-3100 with low pressures. The bearing surface of the bullets stays above the neck and shoulder junction, and with a nice long neck you could push the bullets out futher say a Wyatts Extended Box but we think its not necessary. We have just started testng so I'm jumping the gun a little bit, but I had a little time to kill so heres a preview.
More pictures and information to follow.
