Subject to correction, I believe the 9mm Winchester Ranger T ammunition is a 124-grain +P round. If it is +P, as noted by "kjt," you should not use it in your R9.
As far as 147-grain standard loads, as John has done, I have used them (Remington Golden Sabers) in my R9 without any problems. Increasingly, however, I am leaning toward a 124-grain load, since I often carry a Heckler & Koch P7 as a primary and that pistol's gas-delayed blowback locking system was not designed for a 147-grain round.
