When I tried the N320 it was much more expensive than W231. Like $20 more expensive per pound. I ended up buying a pound on sale with no hazmat, may have been free shipping as well, don't remember now. It ended up being about $10 more than the Winchester, so I took the chance.
I will say I was impressed with how clean it was, but I wasn't impressed enough to spend an extra $10 per pound. IIRC it was $36 vs. $26 for the W231, or about a 30% premium, and that was a sale price.
Now that the prices are closer, and in some cases VV is cheaper, I will buy it again. My problem here is that I've only seen it locally once in five years, so unless I'm willing to drive it ends up being online only. Hazmat and shipping end up bumping the cost too much vs. local alternatives. Sportsman's in Morgantown stocks some VV powder, but that's 170 miles away, so a no-go unless we're up there for a doctors appt.
some don't buy powder currently so I can see if one is already supplied.....
This is my second issue, I'm pretty well stocked up on all the powders I currently use. I was buying IMR 3031 for $38 a pound, but once it's used up I will be looking hard at the VV powders again.
