Excellent info! Thanks alot. I loaded up VV N320 at 4.5, 4.7 & 4.9 grs with a 180 SXT and, as predicted, I hit 166 power factor with 4.5 grs and 170ish power factor with 4.7 grs. I also bought some VV N340 and at 5.6 grains I was way into major with power factors in the 180's. Also, I see what everyone means with the "felt" or "perceived" recoil; N320 feels alot nicer and isn't as jerky. I'll definately us the N320. I'm thinking 3.9 grains behind a 180 grain bullet for IDPA and 4.7grs for USPSA. Has anyone had any cycle problems at 3.9 grains, with a glock 22 or 35? My daughter shoots IDPA with me and a 11 years old it would be nice to hand her something with almost no recoil but that won't cause too many malfunctions, in a G22.

Thank you very much. I think I will start working up from 4.3 grains until I make major with a bit of wiggle room.

After having trouble getting consistant flow through my powder measure, I switched to VV N320 using 180 gr bullets, at the recommendation of several people I shoot USPSA with. I am trying to make major with a Glock 35 and after working up several loads starting at 3.9 grains and ending at 4.3 grains, the max listed, I ran them through my chronograph. Now in my experience I do not expect to get published velocities but these were way off. In fact, at 4.3 grains, the max velocity was off by 200 fps and didn't make major. I was wondering if the weather would have this much of an affect? It was approximately 47 degrees and overcast. On a side note, when I chrono'd my previous load they were within range of my previous documented velocities. I like the VV powder since it measures so nicely, almost no variation between drops, and wondered what loads will make major? Would VV N340 work better? Any help will be appreciated.
