Lee auto disk power meeasure

Hi, I'm new to the forum. I have a question for those of you who use lee safety auto disk. I'm using 115 gr lead round nose bullets with Winchester 231 powder. The minimum and maximum load are 4.3 to 4.8 gr. when I use the .40 cc disc hole , I get a reading of 4.5 or 4.6 gr. this is a good mid range load. The question is how do I achieve the minimum load ? The next hold down is .37 cc , and this gives me a 3.8 gr load. This is under the minimum (4.3) gr minimum that winchester 231 recommends.
