A few weeks ago I bought a new Remington 700 ss in 7 mmsaum. I took a doe with it with a factory load that used 160 gr. Partition. I'm going to load for this rifle and I was thinking about using either 140 gr. accubonds or partitions. What's a good powder for this? By the way. that 160 gr. Partition knocked that doe flat at about 200 yards.
