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.
