[QUOTE="Fiftydriver, post: 176279, member: 10"] Surplus powders that work well are WC872 and WC860. I have not personally used 860 but I have some customers that have. With the 169.5 gr ULD RBBT, there are several commerical powders that work well also. Retumbo is probably the very best. US869 also works well but its a bit sensitive to temp changes as are the surplus powders. Rl-25 should also be usible but you will need to watch as you can pressure out easily with this class of powder. I have not used 7828 SSC but it is similiar in burn rate so it would probably work as well with a properly developed load. I have not used T870 but it to would well as its a very slow burning powder. I have no load data for it. Retumbo is the very best powder out there for the 7mm RUM with 140 to 160 gr bullets. It works just as well for the 270 AM with 169.5 gr bullets. Kirby Allen(50) [/QUOTE]
