TX I have tried 65 gr of IMR 4831 (max for Nosler) with the 150 Partition previously in the 7 mag and not gotten to 3000. I have started to play with RL23 and I think it will allow me to get the 160 over 3000. With a very moderate charge the RL23 pushed 140's 2970 at the muzzle. Finding RL26 near me right now is a pretty tough task!
