I have no desire to load and shoot a load in excess of 1200 fps preferring something under. Because I trusted published data I never saw a need to test. That assumption may or may not be correct. In fact we do not know this test data reflects what goes on in a typical barrel. To that, note the bore diameter of the test barrel of .614, That is a bit tighter than a typical 20, at least the one's I own which are closer to .618. Not much difference but how much does it take to uptick pressures?
I do plan on submitting additional losds for testing and included will be my base load with a Win primer.
