What powder are you having the issue with? Stick powders can be a PITA but 5 gr differences are over the top. I've loaded thousands upon thousands of rounds with the same powder throw without a problem.

When you make a 'throw', you might try rapping the handle quickly a second time to settle the measured load. I'm not sure what you mean by 'additional spacer'. Perhaps you could elaborate. Also, take a look at you-tube. You'll find a number of good vids that show how to get a good measurement.

inside the the throw tube you have the large rifle case mouth and additional spacer to activate the powder measure completely I am using imr4451

I'm using this on a progressive press so it has linkage attached to it
