I might be the only guy alive who never loaded a drop of 4320. No reason, just the way it worked out over 50 years of experimenting with darn near every other powder under the sun. Strange.
That makes two of us. I actually have 4 or 5 pounds of it in the older metal IMR cans, and have just never used it. My only excuse is that I dislike metering 3031 and 4064 and just mentally lumped 4320 in the same category, but reading here, sounds like that was a mistake. I'll have to load some up and try it since I have a bunch of cartridges it should work in.
One of the comments above about 4320 metering like ball powder has me curious, and I can't check till I get home. Does it really meter that well? Must be a really short cut powder then I'd guess?
