I'm looking for a website that has photos comparing different types of smokeless powders. Specifically AA#9 vs. IMR-4227 vs. H110 vs. Win 296. I have some .30 carbine reloads, and I'm trying to identify what the powder is so I can judge if the loads are OK.
There's 11.5 grains of powder in them, and the cases are full right up to the bullet base, might even be compressed. The guy I got them from couldn't recall what the powder was, but judging from the weight and volume, I'm kinda thinking AA#9, but I don't have any to compare to.
Anybody know of a good place that has closeup photos of powder types?
Many thanks!!!
