40SW

150 JHP @1.105" Max 8.2

180 JHP @1.125" Max 7.0

Keep in mind, you're using plated bullets that generally run higher velocities at HIGHER PRESSURE with a given powder charge than jacketed bullets, and the 150 data is for a bullet 5 grains lighter than the bullet you are using. Also keep in mind that I could have made a typo. Work up your loads using safe practices.

Also, I have never tried these loads so I can't vouch for whether they would be "good" or not.
