I didn't know Don passed away.
We met maybe eight years ago at the SHOT Show, when Don asked if I'd be there and if so, if we could meet. We did and had a great conversation. At the time one of the things he was working on was my empirically formulated 4-to-1 Formula: Any difference in powder capacity in a centerfire rifle case of rhe SAME caliber at the SAME pressure results in 1/4 that difference in muzzle velocity, with the same bullet.
Don figured out why the formula worked--at least closely enough for practical purposes--and was gracious enough to ask to cite my original work when publishing his article. Of course I said GREAT!
We saw each other at various other gatherings over the next few years, and always had very interesting and enjoyable conversations, mostly about ballistics but sometimes about life in general, and kept in contact with e-mails until a couple of years ago.
He was a gentleman and a scholar, in the best sense of both words.
