Bullets.com is in the final close out process, they have VV N310 on closeout for $21.06/lb. Their HazMat is $20, and shipping $9.95. So 4 lbs of this powder will run you $114.19, or $28.55 per lb. That's not bad at all! Of course, not everyone can buy 4 lbs at a time, but that's still a pretty good deal...while it lasts. Even better if there are a few folks in your local area that want to share the order.
