I used 67grns RL-15 and 300gr NF softs on my last Safari. Chrono'ed just over 2500 average from a model 70 Safari Express. The load performed very well as did the NF softs. All those recovered were a perfect mushroom. Haven't had time to weight them yet but would guess they all retained 90%+. IMO one of the better hunting soft points around. Was using 250 grn A-Frames out of my 338 and IMO the NF's are the better bullet. They had a much more consistent mushroom then the swift's from those recovered.
