My pressures were running high, hpr at 280 and lpr at 110, and it should be lower than that. I broke down the lpr and poppet assembly, relubed, and reassembled. That didn't help much/at all. It needed it though, the grease in there had passed its prime.
Then I started working the dwell up. I've got a virtue board and had it set to 7, which I thought meant 7ms for a virtue, and should be the dwell for an nme. That increased the velocity significantly. I'm now running 9ms and was able to lower the lpr to just under 100psi.
It's a fairly new NME and has no breach wear, so maybe it needs to break in. I'm going to put 10 cases through it and see if I can drop the pressures after that, because I'm still running a bit too high in both the lpr and hpr. I'll also try changing the ram orings if it doesn't improve.
