I load for a couple 10MM and have good luck with #7, Silhouette and Longshot. As I can't leave well enough alone I felt the need to try some different powders. I like Speed. Looking at VV's load data I was impressed with their 180gr loads with N-105. So, I tracked down a pound thinking I was going to find magic in both accuracy and speed. Then I read all the load data and posts here using N-105. It appears that VV's data is way over stated as far as velocity goes. If I stay within the safe range according to VV I will have weak/mouse fart loads and if I desire to get some speed I will have to go well above VV's published data. Not real happy with either choice. Now I have to figure out what to do with it.
