[QUOTE="mrultramag, post: 101936, member: 4467"] That temp issue probably rules out RL25 then. I have shot that load I stated at 90 plus degrees but have not shot it when real cold. It does drop some velocity though. Ramshot magnum powder might be interesting; it's supposed to be temp stable. As you know, most of the hodgdon powders are supposedly temp stable. Maybe wait for US869 to arrive on the shelves. I think that with the right powder your velocity goals are not overly optimistic. 3500 w/140's should be attainable with a pretty safe load. Hell they do it with the STW but at fairly high pressure. [/QUOTE]
