Every 7 Rem Mag that I've had was throated to allpe a 160 NPT to be seated to the base of the neck, hence essentially 7 Wby velocities via a little more powder capacity.
RL22, 25 & 26 almost always give best velocities & usually good/ best accuracy, IME.
7828 is about next on the list.

Reloader 25 has always been the good magic powder for all of my 7mm Rem mag. loads. However, Scheels in Great Falls had StaBALL HD for $37. xx/lb, and I bought 3lbs to try to duplicate the performance of my R-25 loads.
The StaBALL HD is touted as being temperature insensitive, to have a copper fouling reducing ingredient, will provide good load density in the 7mm mag case and is Available, so I am going to try it.

I've had good results on elk with the 160 Partition in a NULA chambered in 7x61 Sharpe & Hart. While loading data varies a little from the 7mm Remington Magnum, ballistically the cartridges are almost identical. However, I've had three barrels on my rifle. The first two were very accurate with the 160 Partition. The most recent barrel doesn't shoot this bullet with the same degree of accuracy the others were capable of, but I've found this to be pretty common with other barrels and Partitions.
A Sendero in 7mm Remington Magnum is reasonably accurate with the 160 Partition; fine for hunting, but other bullets are more accurate. Still, Partitions are always worth trying. I could never get PT’s to shoot in anything I tried. And, I tried a lot.

To follow up with my preliminary results using StaBALL HD under 160 gr. AccuBonds in my 7mm Rem. Mag., I achieved a multi string average velocity of 3009 ft./sec. - just short of using manual max loads. Unfortunately, my groups were fair at best and the magic sweet spot has eluded me. Maybe this spring I can chase this a little bit more, but right now I don’t feel like messing with it.

Partitions generally shoot very well in every rifle I've tried them in. 6mm/243 to 375H&H.

I've tried Partitions in many cartridges and rifles. Accuracy results were very good in about 50% of them, about the same percentage as other bullets? (just a guess). Poor to mediocre in the rest.

Did you check bullet runout/alignment? I've found Partitions to be more sensitive than other bullets to being seated "crooked."

I have also found a Partition likes it when you put the gas to it as well.

Oh, yeah, whether using a little more powder--or a slightly faster powder.
The last was the long-time advice of Gail Root, the head designer at Nosler for many years.

I usually lean towards the faster side of powders and lean on it. The cartridges I have used them in are cartridges where IMR-4064 is a good fit. Regardless of cartridge being loaded or bullet in that cartridge I seem to find accuracy easier with faster powders......if that makes sense.
