Anyone have any data for loading the 7mm Ultra Mag with 150 grain TSX bullets??
Thanks!!

Not for the 150 tsx. I load the 7 RUM w/ 150 nosler partitions, Rem case, Fed 215 primer, 95 gr RL25, OAL 3.670 or as long as your magazine will allow. Chrono's at 15 ft @ 3450 fps ave. 3 shot groups at 100 3/4 in. Work up from waaaay below Like start at 85 gr. Each gun is different and different lots of powder are different. and....your using a pretty hard bullet that might build pressure quickly. might be worth a try w/ RL 25. If your shooting a rem 700, slight ejector marks on the head of the brass tell you your too hot. Back off or you'll ruin your brass with expanded primer pockets. Might try some Ramshot Magnum powder or Hodgdon Retumbo or Accurate 8700 as well. I heard a tale that hodgdon is coming out with a new powder in 2006 that will be similiar to H870. Might be just the ticket for the 7 RUM. I love mine. Many people say it is unpredictable to load for. I haven't found that to be the case.....yet. Good luck. Let us know if you find a tackdriver load.
