I used the 64gr. Winchester Power Points in a Ruger KM77RFP MKII .223 I had that had a 1 in 12" Twist. I loaded them to 2912 FPS with W-748. Accuracy was about an inch for 5 rounds at 100 yards from the bench.

I still load the same load for a buddy. He has used that same load for 2 years now on South Dakota Pronghorns with great success.
