I used 4064 in my Encore whelen barrel. You can get down to 2400 with minimum loads of that with good accuracy. I shot 200 rem corelokt and 200 hornady bullets. I traded my whelen barrel for a 358 winchester a couple of years ago and I really like it. The whelen barrel I had was 24 inches and kicked like a mule. The minimum loads helped some but I like the 26 inch 358 much better.
