For handgun loads I vary my charges by .3gr.  Get to shoot more that way while  finding the perfect load :wink:

I also work in .2 or .3 gr increments for pistol work-ups.  .2gr for faster powders and .3gr for slower powders.

Once I find a load I like, I load that plus & minus 1 tenth to see if there is any improvement.   Then it's done.     Now if it was a rifle load - THEN I would play with OAL some at that  point to see if I could improve it anymore.
