I did manage to call around locally and find some N-340, as Vit is like really scarce around here it seems.
The Power Pistol I have been running for full power target loads at around 140 PF does seem to have a lot of flash, which concerns me in a defense load, add I wanted to get a bit softer at closer to 130PF and not run too dirty.
But if you guys think the Vit is good to go, although it is rated similar to the PP on the burn rates, then I may just splash out the $40 for a pound and get some. I guess I can allwaways run them a bit faster than 1100 if needed, but that seems about average for most factory loads in the range, without going to a plus P load.
Thankfully, I now have some 124 PD JHP bullets to develop loads with, which seem to directly interchange with the 124 XTP expensive bullets.
I am liking the PD bullets, and they will be my main range bullets for a while, no need for anything else.
