JBD, I load for the 223 using the Forster Ultra and the Jennings Mack 20. You will be happy with your choices.
A few words of caution regarding the Mack 20. The instruction booklet is pretty sparse, but there is one small passage regarding electro magnetic interference. Heed the advice. I found the scale very sensitive to EMI to the point where I can't load in my shop which is lit by high output fluorescents. I do my powder measuring in the basement under incandescent light. It seems to make a difference. I noticed once that even my digital watch seemed to affect readings when passed in close proximity to the pan.
Be careful when trickling powder into the pan. There is an opening to the inside of the scale around the stem the platen sits on. Powder tends to bounce out of the pan and down inside. Can't be good. I've taken to either trickling with the pan off the scale or using a small spoon with only one or two grains of powder in it. I think there is also a caution in the instructions about adding very small amounts of weight. The scale tends to ignore tiny changes and automatically zero them out.
Aside from the scale "zero" drifting .1 or .2 grains every couple of minutes and having to be reset I'm quite pleased with it. It has given me good results.
