This gives me a power factor right around 203. It's generally acknowledged that a power factor of 190 is about the minimum you need to reliably move the pin four feet back and all the way off.

We get into a lot of 'discussions' about the various benefits of smaller bullet moving faster vs bigger bullets moving slower. But most of the guys I shoot with are moving into the bigger bullets slower camp. Even the top 357 shooters are using 180 gr bullets.
Straying OT a bit, but at what point are the pins replaced with new ones? I have shot a few on a recreational basis and have wondered how much effect the extra weight of bullets stuck in them impedes their movement off the table.
