I wouldn't have thought of using Big Game, but obviously it works!
By the way, 100-grain Nosler Partitions in Weatherby factory loads regualrly shot in the 5/8" range in my rifle. The buys at Nosler tell me their test standards are the same for Partitions as any of their other bullets. I suspect one of the reasons some people don't get good accuracy out of Partitions is they don't expect it, so don't take the time to try different stuff, whether seating depth or different powders.
I was surprised at the group, not expecting it. It's only a three shot, but I'll shoot some more to make sure it's not a fluke.
I've got good results with the 90 gr. SSII's. .7" at a hundred. For now, I think I'm going to give the 85 gr. NPT's a run. I use a 250 yd. zero, and am approx. 1.5" hi at both 100 and 200 yds. At 300, 350 and 400 yds., I just have to remember 3", 6", and 12" drop, respectively. This combo produces 1,000 ft. pounds of energy out to 375 yds., so it's not an ultra long range deer load.
