Tank1949,
The JDS is operated by a special powder funnel that has a hole already smaller than your 223 neck ID. Also, bear in mind there are short cut and smaller grains than just 4064-sized ones. I think you'll find something that works well for 223 with it. I've used IMR4198, RL 10X and Benchmark and H322 with it in .223 without issues that I recall.
