However, FPE also depends on barrel length, so a 14" barrel would drastically reduce the power compared to the 28" barrel on the MACR that Jeff tested just a few days ago. Quote from: rsterne on January 12, 2017, 02:20:31 PM FPE is pretty much in direct proportion to pressure, so 4500 psi should be 50% more FPE than 3000 psi. I gave up because I couldn't understand any of the important information, even the caliber was almost impossible to understand. PS - I just tried to listen to the promotional video on the Baracuda, and the audio quality is terrible. Something doesn't add up, if their factory data is so much different than the results Jeff got. and dropping the pressure down to 3000 psi should drop that down to just 52 FPE, not 100. 357 cal, which was 91 FPE at 4000 psi, to just 65 FPE. but taking the test that Jeff did and cutting the barrel length in half should reduce the best FPE he got in. Since the cartridge volume is so small, the usual rule of thumb for maximum power that half the barrel length would result in half the FPE doesn't apply.
