58.0/IMR4350/150NBT/CCI200

I just picked up an older [1968] Winchester 70 this summer, clean, nice rifle; mounted a period correct Redfield 4-12 scope I had laying around.

I tried a few different loads surrounding the Nosler 150 grain Ballistic Tip using Varget, IMR4064, IMR4350, and a few other powders I had laying around. IMR 4350 seemed to be the most consistently accurate. At 50 grains, Varget would throw two nearly through one hole, then would always toss the third round opening up the groups to around two inches. IMR 4064 just plain sucked, I couldn't keep anything under about two inches despite the powder charge. As for the IMR 4350, 58 grains seemed to be the magic number, as it will CONSISTENTLY put FIVE shots into about an inch at 100 yards over and over again.

I seated the 150NBT's to .010" short of the lands, as is customary for my reloads when I'm searching for accuracy.
