I was ultra disappointed to hear of the demise of IMR-4320. It's my go-to 22-250 powder along with a 55 gr. Ballistic Tip. Have used it with satisfaction in a variety of other applications as well. I have burn rate charts. I know what other powders are in that ball park. But what's the best powder to use when I'd really like to get my hands on some IMR-4320 and it's unobtanium ? What a bummer. Think I only have about a pound left.
