First, I'm new to shotshell loading; still learning. I'd like to get a bushing for Clays. Looking to throw 18.8 -19.4 grains under 1 1/8 oz shot (have this bushing already) for 12 ga. The powder charge is max based on data I have. The press also came with a bushing marked Red Dot. I understand Hornady might have what I need. Found a chart for Hornady 366 press bushing; is this helpful in my case? TIA!
