The last of the AA7 is out , i'm sticking with the N340 now, but i'll get some faster VV next time.. VihtaVuori lists N320 , N340 and N350, i went with the middle.
Spring was/is installed as you describe
No lube, just plenty of FP10, it sweats when it warms, so i'm pretty sure it's wet enough
I'll check the crimp over the weekend, I'm loading 5-600 rounds , brass is tumbling as we speak..
