After reading some of the comments here in my other thread I was persuaded to use Varget rather than Winchester 748 for building up 223 Rem rounds using 69g SMK bullets.
I am using once fired Lake City brass, trimmed to 1.750" amd CCI #41 military primers. I made 2 batches, one with 24.0g of Varget, and the other with 24.5g of Varget. Overall length was 2.260".
I fired out of two AR's, one with a 16" barrel, and the other with a 24" barrel.
Here are the results:
24.0g avg velocity: 2506 fps (16") ------------- 2788 fps (24")
24.5g avg velocity: 2555 fps (16")-------------- 2859 fps (24")
Both rounds functioned perfectly in both guns. There was no sign of pressure problems. I think the load with 24.0g was shooting about 1/16" better at 100 yards than the 24.5g load, but it might have just been me. I was surprised my velocities were as good as they were, as I thought my Varget load was a little low at 24.0 and 24.5grains, but since I was using military brass, I wanted to make sure I did not go too high.
What is your critique?
