Know the feeling. I've shot ~ $150 in components trying to get 160 Partitions to fly consistently accurate in my 7RM.
Am going to bed the factory stock as a last resort.
I have been shooting and hunting with the 160 gr Nosler Partition in my (2) 7mm Rem Mags that I have owned for 45 years. The rifle I have now (a Custom stocked and smithed Mark X-Parker Hale) has been shooting the 160 gr Partition exclusively for 30 years. I have not hunted as much with this rifle as with some of my Model 70's over the years but the rifle has always performed well although I don't prefer this caliber for elk.
I use a max load of IMR7828 with a magnum primer and the load consistantly shoots sub-MOA groups. I have killed probably a dozen deer and one elk with this rifle. The Partition bullets always performed perfectly for me with all game in this caliber.
I just bought a box of 250 grain .338 Accubonds for my .340 Weatherby Mag and will be developing loads for this rifle soon. I am looking forward to seeing how they shoot in this rifle.
