I have a Speer #13
It shows 15.1g max (.357) for 140g JHP. It says to reduce the laid by 1.0g for 146g JHP-SWC
But only 12.1g fits in the case. The book doesn’t indicate not indicate a compressed load. But 12.1 is definitely going to be compressed 🙁
I’m not comfortable using it, but it is a book load.
