Believe it or not but the powder pics on Vihtavuori's website on each powder page are pictures of that specific powder-- so you can get a very good idea of kernel size and shape.
Vihtavuori is good stuff, I've been using N133 for 40-55gr bullets in 223s for many years now, 3N38 for my uspsa open blaster, N320 in my uspsa limited gun, and N120 in my .20 Vartarg. All have been very consistent and very clean burning.
I haven't tried any of the N5XX series yet but will probably give them a whirl when I burn through my current stash of AR Comp & RL16. While I love those 2 powders, Alliant powers are ridiculously priced right now, and furthermore all Alliant consumer canister powders are going to be unavailable for the near future according to what Powder Valley was told by Vista; apparently all outstanding dealer orders with Vista for Alliant have been cancelled with no ETA for when they can be placed again.
