I am not sure why the N340 did better I'd like to hear thoughts on that also. I did 5 different runs of N320 tweaking powder charges, primers, and OAL. It was a softer shooting round but always had just enough gas cutting to leave enough lead that it worked it's way down the barrel. The bullets I recovered with the N340 didn't show the gas cutting. The accuracy was just as good, but I had to shoot a mag of FMJ every 50 rounds to clear the decks. The N340 has more felt recoil. The guy at Badman Bullets said he thought that was due to N340 not being completely burned up upon the bullet exiting the 4.4 inch barrel. The N320 definitely fires slightly cleaner. Weird note about my sigs...factory wise they seem to like remington; the dirtier the better. My shield prefers blazer and PMC. My Bersa thunder 40 UC hates everything haha.

The chrony was a good addition to the testing I think. My tests feel more definitive now. I'm excited to try it with my 22-250.
