I hope you're hunting elk, moose or bears when you are using the 175 grain and 160 grain bullets in your 7mm Remington magnum 'cause those bullets are very heavily constructed and certainly not the best bullets for deer.
You mentioned "high velocity" in your post, but you're literally weighing the fine 7mm Rem. Mag. down with those heavy-for-the-caliber bullets and losing much of the advantages of that round's "high velocity" characteristics.
It's generally acknowledged by most people that the "deer bullet" for the 7mm round is the 139/140 grain bullets that not only "shines" in the 7mm persuasion, but does a fine job of killing deer and like sized animals if the bullet is placed in the game's "kill zone".
Using the 139/140 grain 7mm bullets, your 7mm Remington Magnum rifle can achieve muzzle velocities exceeding 3,100 fps using IMR4350 or IMR4831. In fact, one of my reloading manuals indicates their "accuracy load" for the 140 grain bullet is 66.0 grains of IMR4350 yielding a MV of 3133 fps with 52,000 C.U.P. THIS IS A MAXIMUM LOAD AND MAY BE DANGEROUS IN YOUR RIFLE. WORK UP TO THIS LOAD SLOWLY WHILE WATCHING FOR HIGH PRESSURE SIGNS.
I agree with your choice of the BRAND of bullets you're using (Nosler Partition), but I wonder about the WEIGHT of the bullets you're using. I use Nosler bullets exclusively for all my big game loads. I've found that Nosler's bullet performance is excellent regardless of range or velocity.
Strength & Honor...
