I have used the 175gr Nosler in my 7 Mag for 30 years. It was the only bullet Warren Page used in his Mashburn Mag.
My rifle has a long throat and I load it to almost 3,000 fps. I could exceed 3,000 fps with the old style Nosler and still have a few. Last year I drew elk tags in 4 States and took four big bulls with four shots. I use the Hornady 175 for deer and critters smaller then elk. I might add that both bullets are very accurate in my rifle and shoot flatter then one might think. The 175gr Nosler penetrates on a par with the 200gr Nosler in a 300 Win. The 175,s work well in my .284 at 2,750 fps also. I use them when I am shooting over feeders and food plots and its bang flop every time.
I would sure give the 175 a try if were looking for an all around bullet for a 7 mm rifle.
