Rusa,
In one word, yes. The 7mm RemMag is an excellent round for hunting at long range. I have fond affection for the round and have used one for informal target and hunting for almost a decade.
I have reloaded for my Sendero and have shot bullets from 110gr to 168gr. All my deer were taken with the 150gr Nosler Ballistic Tip. Powders I have used are IMR's 4320, 4350, 4831, 7828. Hodgdon's Varget, 414, 4350, 4831 & SC vers., 1000. Reliant's 19 and 22(my favorite). The cartridge is versatile, accurate and has the velocity and energy needed for LR big game hunting or target shooting.
With all the thousands of dollars worth of reloading components that I have sent down my barrel, I have finally burnt my out. I figure on close to 1700 rds and time for another tube. This is one rifle/cartridge that I don't plan on being without. HAGO, Johnny K.
