With the same primers, powder and charge, and bullets, same chrono, same strain gage, etc, both made the same speed and pressure and accuracy. I dont buy the whole case shape/special shoulder/ no belt idea. Here is one thing I have learned and will test against any data at any time :
Primers, gun powder, and bullets do not respond to advertising !
They will do what they do.
And another thing.....I dont think we need any more new calibers until we starting burning something other than smokeless powder. The perceived advantages of several of these new calibers, the real advantage is less than the noise in the testing.
All that coming from a man who must have at least 15 wildcats in 9.3 ! grin

P.S. just remebered.....that particular barrel in the test shot better in every way with Ramshot Hunter than all the other powders.


My understanding is that it wasn't an accuracy test; but I brought up in the past that the short powder column and 30 degree shoulder didn't seem to have a measurable effect on accuracy or getting the fuel "lit" with more "efficiency".

Everything appeared to be pretty much same/same, with the usual small uncontrollable variables.
