I did exactly that yesterday..... loaded some incremental 60gr loads for my .223 with 748 using a LEE dipper and electronic scale. You can dip very consistently with 748 and add a few kernels by hand if need be. It was quicker for me to do it this way than to set up my powder measure for such few loads.
I was done in no time.....
That's what I'm talkin about. If I load 40 rounds it'll be a BIG day.
