My kids and I took several whitetails in Nebraska and a couple in Colorado with the 7mm Rem Mag. with 140 Partitions and they worked as advertised. My wife started out using the 140 BTs in her .280 and switched to Partitions as the BTs were ruining too much meat. My kids and grand-kids use the 120 BTs in their 7mm-08s at moderate velocities and they work fine, but I would be hesitant to use them in the 7 Mags, especially if you are hunting primarily for meat...
