Best powder for cast pistol bullets.

[Mbaker78]

The lyman manuals highlight the most accurate loads for each bullet. They have 2 manuals. One is dedicated only for lead bullets and it's an excellent loading manual.

If you have this manual, does it have any data for 300aac subsonic? Specifically lighter weight subs? I’d like to work up something subsonic with the lee 312-160, with or without a gas check
