G'Day Fella's,

FYI Casper50, in the current edition of Wolfe Publishing's "Handloader" magazine (#333, August 2021, page 12), there is a brief article by Gil Sengel on the 12.7 x 70 (.500 Jeffery or .500 Schuler) cartridge.

Let me know if you can't get your hands on a copy of this article, and I can scan and email you a copy of it.

Avagreatweekendeh!
