So I've decided the price difference of $10 over 1,500+ rounds wasn't too big of a deal and decided to buy some VV N320.
I loaded 4.0gr of N320 in 9mm 124gr Ranier RN, win primers, 1.150 OAL
Quickload predicts this to be 80% of max pressure, and 1062fps
These would not quite cycle the slide of an HK P30L, I didn't chrono it since it didn't even cycle.
I'm going to try 4.2gr (90% of max pressure, 1098fps)
Has anyone else around here used N320 for 9mm, especially in heavier to cycle pistols?
I may give up on using N320 for this particular combo and switch to N340 I have, I've loaded up a few at 4.9gr of N340 (81% of max pressure, 1107fps)
and some at 5.1gr of N340 (90% of max pressure, 1145fps)
I will have to see how those do sometime this week.
The reason I don't like hanging too close to max is because I used to load 9mm with bullseye towards the higher end and being dumb used Lee's number that came with their die set. Now I have a bit of bolt face erosion to show for it. Yup, should have checked for other signs of pressure closer at first.
