JGorski,
You got me again.
Yes, my load development centers on the assumption that 2000MR approx = CFE223 it proved to be close enough in my 308ARs, so i went with the same assumption.
I also noted that the 30-06 loads are only a 1.5-3grs higher than the high end loads i worked up in my 308ARs.
The 53.5gr of 2000MR also shows NO Pressure signs. The primer is nice and round, and i cleaned an SR-1 reduced target with it.
As usual, every rifle/chamber is different, work up while watching for pressure signs, blahm blah, blah.
