In the early 1980s, I was fortunate to work in an engineering prototype industry developing electro-magnetic peripheral products. So, I have always been fascinated with innovations, and
trying them has never been an issue.
In 2021, I put together a budget project in .257 WBY for my first .25 caliber/cartridge. It was primarily built to propel the heavies—131 BJ and Berger 133/135. Then came the Hornady 134 (and now the 138), followed by the 145 Black Hole and the 163 Chinchage (thanks to
@Bghunter338 for the introduction). I jumped to the 145 Black Hole with very good pressure test results but temporarily put it on hold to explore the 163 Chinchaga, which also had very promising test results.
Chinchaga is supposedly going to start building the 180s; when available, I will also explore the Hornady 138. There are naysayers here who were questioning why I would go heavier than the 145s, but I simply responded because I could. Honestly, I do not care because it is my time, effort, and money—and that's the beauty of having plenty of choices to choose from and the freedom to choose.
