I 'm relativity new to reloading (started in 2016). I bought a 9mm pistol and decided to reload ammo for it. I done a lot of research and decided on a starting load (minimum) of 3.3 grains of 700x powder. I loaded up one mag full (16 rounds) and while I was at it, I loaded up 16 rounds with 3.5 grains of the same powder. I shot the 3.3 first and then the 3.5. What a difference!!! I can't believe the difference in .2 grain of powder!! That's a 7 inch paper plate. I guess I found the "recipe" the CZ really likes!!
