I'm awfully fond of IMR4831 in the 7mm Rem Mag. With 140 gr bullets, I've also used H4831 (war surplus) and IMR4350 in Remington 700, Sako L61R, and Browning A-Bolt rifles.
My current fave load with the 140 TTSX is 67/IMR4831 for 3214 fps out of a Remington 700 SS with a 24" barrel. Cases are R-P and the primer is the Federal Magnum. With this recipe, I've taken my best whitetail, my 2nd and 3rd best mulies, and my only Roosevelt elk. In 2 weeks, I'll be chasing a tule elk with the same outfit.
