Speer Gold Dot Duty Rifle 75gr load?

I agree it's nuts. My notes show 5 MOA, but maybe I goofed and it was less. Still, it wasn't even on paper at 600 when the other loads were relatively close.
Maybe it was only 4? It certainly wasn't 3 because I had to dial up from all the others.

Regardless I'm gonna have to go back when I have more time and test again.

That does sound strange. Speer 75gr GD should be getting ~2500fps out of a 16" bbl. Considering that IMI is 5.56 pressure and a pretty hot load, Im surprised the other .223 loads were holding close to it.

For reference I'm getting 2440 out of a 14.5" barrel and 2130 fps out of a 10.5" barrel with the 75 gr gold dot. They were grouping better than 2 MOA out to 200, but I have not tested beyond that. It chronos about 170 fps slower than mk262 out of the 14.5" barrels. 500 feet, 65 degrees.
