For everyone suggesting 7828 I would like to add we have used it with 200 SMK's and there is room left over. Velocity is good but there remains potential in that space. We will check the length to jammed this weekend and proceed from there. Your numbers for seating depth will be followed.
I have used 7828 with good results but have found that in my rifle, Retumbo has given me the lowest ES, and excellent temperature stability which ranges from 15-80 degrees through my shooting season. It does fill the case, and there are no pressure signs. This same load also produces the same velocity, ES, and accuracy using 210 Nosler Long Rang Accubonds seated .050" off the lands but I have not yet tested them past 500 yards. The 210 Bergers shoot very well, tested out to 1450 yards.
